At the end of the day, Prey takes my top spot of favorite game on the PlayStation 4 system.
It's a game made by the very best developers in the industry.
The survival horror aspects are top notch, the scares are aplenty; one jump scare in particular scared the living poop out of me.
The evolution system is extremely effective, powers are varied, weapons are varied.
The physics feel...good. like they do in half life, giving the games environment a feeling of gravity and authenticity that you only see in the creme of la crop games, usually in the past, made exclusively by Valve, as if Valve was like Pixar in the animated film arena. Note: I mention valve only because I compare this game to the best of their games; Prey is made by developers at Bethesda.
I love this game like a kid loves a teddy bear.
