I am getting a 21" Sony Trinitron CRT today for my PS2 cos I got tired of some PS2 games looking like vomit on my monitor. I will make a pic of my setup (PC/PS2/PS3) later and post it because.
Deus Ex (2000) - a game that pushes the boundaries of what the video game medium is capable of to a degree unmatched to this very day.
