1. Metal Gear Solid 2 -- I have the demo. The demo alone is better and has more replay value than most full-length games out now. Hell, I've only beaten it three times, but I've played it countless times! I just like messing around with stuff.
2. Devil May Cry -- Come see what I'm talking about... (BTW, if you don't see these, you're crazy.)
