There is quite a bit to say about Darkout. I'll try to be as non-partisan as possible.
With the explosion of greenlight games and the large number of 'Metroidvania' sandbox style games on Steam, it's hard to make one stand out from the rest. Darkout, like Terraria, or Starbound, takes yet another approach at these sandbox style games, but, of course, is still very much the same.
Indeed, Darkout is much the same old grind. Spending hour upon relentless hour, mining through piles of the same dirt, and rock, only to fill your inventory and discard, rinse and repeat. Just enough to get you the resources to build an elevator to reach the depths of the shaft you just dug. With the same old spotty mouse targeting as others, a horrible grouping system for mining, a terribly inaccurate crafting system, and a slew of other annoying bugs, it is tedious at best during these hours, searching for resources, and can often be a real chore, during these times, to play.
It has more base in sci-fi than others in it's genre, even more so than Starbound, only short of having a spaceship and being able to explore a number of alien worlds. With crafting devices like the Combinator, the Molder, and the Chem-Lab, weapons such as the Laser gun, and fusion based power devices, it's a sci-fi sandbox geek's dream come true. Coupled with a fragmented, yet deeply frightening storyline, and some absolutely dazzling light effects and much better graphics and visuals, overall, Darkout is a step ahead of the rest. With a fairly extensive research/tech/crafting tree and some fun and interesting exploratory and combat scenarios, heavily focused on the use of light, Darkout is, again, in a class of it's own.http://steamcommunity.com/sharedfiles/filedetails/?id=259009998http://steamcommunity.com/sharedfiles/filedetails/?id=259011002
A key thing to remember is that being another 'early release' title, or beta, at this point, the small Independent Developers, Allgraf
are slowly, but surely, diligently churning through bug fixes and adding new content for upcoming stages of the game, including more story, new monsters and biomes and of course, more craft items.
While I might not recommend it, at this time, for anyone who is easily frustrated, I am excited for the future of this great game, and can imagine recommending it to any player who enjoys this genre of game, and possibly even players who don't, upon the game's completion.
In short, after all of that, Darkout is an absolute GEM. Recommended? Definitely.
