I'm a bigger fan of Xbox and Xbox 360 more than PlayStation 2 & 3, but the PSX was probably the greatest system I've ever owned. So many great games. Crash Bandicoot (all of 'em), Metal Gear Solid, Spyro, Medieval, Gex: Enter The Gecko, Resident Evil 2, Tomb Raider 1 & 2 (before they started going downhill), Thrasher Skate and Destroy, Twisted f'ing Metal, Wild 9, Die Hard Trilogy, Tekken 3, Syphon Filter, Street Fighter Alpha 2, WWF Warzone, WWF Smackdown 2... I wish I could remember them all.
I never got into Final Fantasy VII, but this was at a time when I was coming from Super Nintendo (I was 12 or 13 I think), so all I wanted to do was platform and shoot stuff. I need to get a PlayStation.
