2006 was a neat game with some particularly cool bits, but 2017 is one of my favorite games of all time and pound for pound is a superior game due to 2017 being a spiritual successor to System Shock 2.
Very different games though, I don’t honestly think they should be compared directly, it was already a weird choice for Prey 2017 to receive the franchise name.
I thought the Green Inferno was perfectly cromulent. I can’t remember much of it, but I didn’t despise it.
