Despite being a game focused on the deep ocean, FarSky has no depth at all. While the concept was interesting, the gameplay and interactivity fail to deliver on more level than one.
To begin, you have the choice of two game modes; the story mode or Creative (three choices, if you count a hardmode of the 'story mode', which increases enemy activity). The story mode revolves around the extremely bland main character, Nathan, who must recollect pieces of his submarine in order to rebuild it and get rescued. Submarine pieces are shown on the map (unless it's hardmode), and in order to reach the later ones, you need to craft better gear. However, the progression in this game is very flat, because getting this 'better gear' simply requires nothing more than a short cruise for some minerals. The gear solely gives a straight stat boost, making it very uninteresting. You can even clear the game with just the second tier gear; the copper helmet easily allows you to reach some of the lowest areas of the map for the sub pieces. Collecting the pieces is also a very quick process; my first completely blind run only took me roughly one hour.
Survival mechanics are nearly non existent. You have an oxygen meter which must be refilled by entering a base, and a hunger meter which is refilled by eating. Gathering food is so terribly easy and generic that the hunger meter might as well not even be there.
Creativity and map generation are both very limited. You cannot destroy any of the terrain, nor can you reform it. You can construct underwater bases, using floors, glass walls, and pillars. However, I feel there is no reason to do so, since the starting base has enough to get you through the game, and there is hardly anything that you can do with extra bases or space. I cleared my first run only using the starter base and nothing more.
The combat is simply terrible. Normally I have a fear of the deep ocean, but after I saw how the AI fights, I was laughing when a great white was spazzing and flinging himself around me like an angry bee. Each and every enemy has the same exact attack pattern if they decide to target you; charge the player, either player gets hit or enemy gets hit (charging enemies who are hit by the player get completely halted...even if it's a kraken), pass by/suddenly start dancing around the player until hit again, repeat. None of the fights are interesting or tense in the slightest, and they're always all the exact same. I also want to add that when you use the knife, you don't even have to aim at the enemy. You can swing in any direction and they'll always get hit if they're close.
There's no replayability either. The map generation is very boring and every single map looks extremely identical, so you really have no reason to re do the story unless you're playing hardmode or you have some strange fascination with this game. Creative mode allows you to edit some settings like enemy activity, day/night length, and what items you spawn with (by using coins you find in the story), but it does not create a new or fun experience at all. I was so desperate for something to do that I even did a speedrun because the lack of content. (Don't mean to toot my own horn here...but 14 minutes! BRR BRR BRR!)
So, if the message wasn't already clear enough, I cannot find anything to recommend about this game, besides being one of the very few games I've played that takes place entirely under water. Extremely short story, heavy restrictions on creativity, laughable combat, and a general lack of content prevent this game from having any unique or purchase-worthy qualities.
