About This Game

Eidolon is a game about exploring a mysterious landscape and uncovering the stories of the people who lived there once before. It is a game about history, curiosity, interconnectedness, and the slow and inevitable beauty of life.

You will be dropped into the dreary and mystical Western Washington circa 2400 c.e. with little to guide your way. Awaiting you is a vast landscape filled with wildlife, edible plants, and the memories of our now-dead culture—stored in artefacts such as journals, sketchbooks, newspapers, zines, brochures, transcripts, blogs, and more. Collect these memories and piece together what happened to these people.

  • Over 150 documents telling the interconnected stories of dozens of characters across hundreds of years.
  • An enormous, hand-sculpted Western Washington that takes multiple hours to cross.
  • Day/night cycle and dynamic weather.
  • Varied flora and fauna (both predators and prey).

I really want to recommend this game, but I can't. It's pretty (for 2003), expansive (enormous and empty), has a good story (chopped up and scattered over literally hundreds of miles of identical forest), and has a nice blend of exploration and exposition (gimmicky survival elements slapped over a walking simulator).

Joking aside, I honestly can't recommend this game to a wide audience. Yes, it has a good story, one that is leagues better than that of a lot of modern games, but even though that story is so interesting, the method of actually uncovering the story is painfully dull. I do like it when a game rewards exploration, and I love it when a game will focus on story rather than the old tried-and-true 'shoot anything that's not the same color as you', but the massive amount of story (150+ items, or so I hear) is diluted so badly by the amount of walking you need to do to find them that even though I was hooked, I couldn't come back to it after a while because finding another thread of the story was not worth holding down my shift and W keys (yes, I know there are auto-walk and auto-run settings, but don't you think that's a symptom of the problem?) for another half hour, occasionally stopping to click on story fragments to watch the green flare point to the next story fragment or eat some fish.

It seems like Eidolon is trying to marry purely story/exploration based games like Kentucky Route Zero and solo survival games like The Forest, and I can't say I'm a huge fan of what resulted from it. The survival mechanics are barebones, but in such a way that it's not an added challenge to survive a day, more of just an added 'collect these unrelated items to continue' minigame. I won't rip on survival mechanics being unrealistic, they're minimalistic and that's understandable, but it seems like it's too easy to survive. All you need to be able to run for a day is two cooked fish, that's it, and after you find the fishing rod, you can get fish within about a minute or two of walking from nearly any point on the map. In fact, the only ways to die are starving (via illness or stubbornness), falling to your death, getting mauled by a bear (I never saw one), and freezing to death. If you don't jump off cliffs continuously, catch more than one fish a day or press E every time you see a prompt come up for mushrooms or berries, and don't stand in water for too long, you won't die. It's more of an added chore than an added challenge.

The art design is sort of a balance between 'minimalistic' and 'lazy', with everything in the game rendered with solid-color polygons, which in the right circumstances can be quite pretty, but most of the time is just bland. For the lazy part, some of the design is just cutting corners. If you're not within 30 yards of a fox, deer, or other animal, they either stand stock-still like a statue or glide around in the same pose a few inches off the ground. Objects are almost always half in the ground, half floating in the air since they don't really accound for local geometry. Skyscraper remnants are strangely even more low-res than the rest of the game, with blurry, off-color edges.

The rest of the game is quite well executed, though, the story is intriguing and engaging, the music is appropriately minimalistic and atmospheric, and the game occasionally has moments where I need to stop and take a screenshot. However, unless you're a fan of walking very long distances to read single pages of books, I can't recommend this game to you. I think that the story would probably be better executed as a collection of vignettes and the rest of the game as a minimalist but immersive and difficult survival game, but that's just me.

What you get out of Eidolon depends heavily on what you put into it. It doesn't present you with any formalised tasks or goals, which I assume accounts for the mixed reviews, but if you're prepared to explore a large environment and piece together the story of what happened there from scattered texts, Eidolon is rewarding and fascinating. The survival elements are rudimentary enough that they don't make up the majority of what you're doing (And I feel like they are there more because of expectation than because they are integral to the design), and leave you mostly to explore and find your way around. I get that this is not what everyone wants from a game, but I got a lot out of it. It helps that it's often stunning to look at, too.

I honestly thought the game was just in the very starting stage of Early Access, so I was giving it a lot of leeway during a stream for all the glitches and lack of depth or immersion - figuring those things would come along once the game progressed through a few initial stages of the first development...

Then one of my viewers dropped the bombshell -- this wasn't a starting Early Access release, it was the finished product...

Ummm, I don't know what to say from there... I'm expecting the project (only guessing) may have simply been abandoned and released as is, which would be fine if noted... but there's so little polish to the game, or the game play, that it simply doesn't feel like a finished (or even developed) game to me...

That strictly my personal opinion, so it may actually appeal to many others. I've been playing so much of The Long Dark lately though, and it IS Early Access, and just so far ahead in how the game feels more complete -- so that likely biased my view and why I honestly thought Eidolon was just in the first steps of development.

I have heard it has a huge map area though, so that may provide some interest for players, and the soundtrack is fairly nice so that might make some relaxing exploration play if that's what you're searching for.

You might want to watch some streams or YouTube videos first to see if the game does appeal to you first..

Eidolon is the sort of game you'll either love or hate. You'll love it if you enjoy a variety of interesting storylines, lore and exploration over a massive world that you can relax in, with a beautiful soundtrack to boot, or you'll hate it as one of those "Walking simulators" with not much to do and survival elements that are weak, if I'm being honest.

It's a good game that could have been made better with more raw gameplay, perhaps being able to scavenge things from the ruins like sheet metal to build shelters and a temperature system so that you could keep warm at night. The notes that you find scaterred throughout the world are the most interesting part to this game, with some dating back centuries and telling the story of what happened to bring you the world that you see now. I'll say this; the story is not what you'd expect and is full of surprises that I'm still discovering, and it's quite deep at times as are some of the characters in them. The notes are spotted as floating green orbs that you walk up to, and you can find more by following the bird that flies above you or clicking on a story piece in your journal and following the green light from that. I would have liked them to be found through searching drawers or in the boots of cars, though I understand why it's done this way. Some of them are hard to read though, so a more 'plain text' version that you could have switched to would've helped. There's also a journal that you can write in and keep track of things, which is a very nice touch.

There are tools in the game as well, things like fishing poles and binoculars, although you only find them as floating white orbs, which is one of the things that could have been done better with crafting or scavenging.

The graphics are very... minimalist, and they actually grew on me. When I bought the game, I did worry about the graphics not being too detailed, but like minecraft's graphics they actually work for the game, though I can still imagine the world being real. Perhaps all too real at times. Standing atop a tall hill and overlooking the rolling forests and ruined cities is actually quite incredible if you find the right place, and the music completes it. The only thing I don't like about it are the animals; they look a little bit derpy at times.

The soundtrack; oh dear, where to begin? There are dozens and dozens of tracks in the game, all of them suited to different places, there's a theme and ambient version for each place and one track for day and night. Some are quite melancholic and others are strangely upbeat or tribal, even sci-fi sounding at times. It's all very ambient and there are no combat tracks or anything too fast paced. They work for the game fantastically and I'd recommend buying the soundtrack for yourselves off of Bandcamp if you like Ambient, or perhaps Wilderness Ambient?

I think having more dangerous animals scattered about would have been nice, I'm not sure why there aren't bears or wolves living in the ruins. Just something to make the game feel more 'alive', like it really is all abandoned and nature is reclaiming it.

Overall, Eidolon is a game I would recommend if you don't mind walking long distances to collect more pieces of the story and if you enjoy lots of story and lore, as well as plenty of deep thinking and wonderful music. If you're looking for a survival game like The Long Dark, this is not it, nor is it a combat focused game. The only game that comes to mind as being similar is Dear Esther, although the two are still different. A good game that could have been a lot more, but it's got just enough to keep me going and has been one of the most inspiring games I've played in my life, hands down.
