Prey is definitely a game that gets incredible word of mouth, it's hard not to love it if you've played it. As with a lot of Arkane's other work it's clear they respect and understand the immersive sim and Prey is absolutely a love letter not just to that genre, but specifically system shock.
It's essentially a spiritual successor to those games, and I really wish they'd named it something accordingly, like Psycho Shock, it would've really given players the right idea, but either way the game that came out is an absolute masterpiece. I'm glad you're enjoying it!
