I just beat Prey.
While I really enjoyed the game, I left it not liking it as much as I initially did. Environment design wasn't as strong as I would've hoped due to the small size of the levels and constant loading stunting the experience from feeling truly interconnected. Enemy variety was disappointing and by the end of the game I ran past most combat encounters since enemies don't have any clever combat engagement variations beyond their basic routines. Even mimics and their cool shape-shifting gimmick weren't put to good use beyond a small scare here and there. I think the most disappointing of all were the characters and their lack of development; not really giving the player any opportunity to identify with anyone, comprehend their motives, or even explore the supposed rich backstory of the narrative. The lack of a strong villain, aside from an uncaring and undecipherable enemy entity, is probably its weakest moment. Also, the bugs on PC were pretty annoying. I had to fight the game from deleting my leveled-up weapons multiple times whenever I'd hit a load point, several quests were bugged and couldn't be completed, and performance was unplayable forcing me to revert my drivers back to the March release.
While that came across more negative than I intended, the game really did have moments where it felt like System Shock 3. The gun-play was pretty rock solid with multiple interesting weapons and grenades, with the recycler charge and gloo gun being pretty inventive. I thoroughly enjoyed the skill customization and felt right at home with the System Shock inspired upgrades while the typhon skill tree presented a new and fun twist. I also really enjoyed the whole material/fabrication system and it was sublime in its intelligent solution to item hoarding and inventory management. The game also did a great job of slowly introducing gameplay concepts and by the end of the game you're given complete control to maximize your character which felt pretty empowering. The ending and was also refreshingly unexpected with amazing possibilities for a sequel which left me pretty excited for the series.
I strongly recommend the game to anyone and while I hate to be reductive I'd probably describe it as a better playing and designed version of BioShock with deeper player customization but lacking the interesting characters and plot of that series.
