I've been a big fan of the Final Fantasy series on playstaion (7,8 and 9). I own all the soundtracks aswell. I've played through Metal Gear 1 & 2. The first is incredible despite the graphics, which were impressive at the time. The preview of MGS 4 I posted a few weeks back is mind blowing (graphicaly speaking). I'm sure the game will be very good. I love cars & racing, so I have a past with Gran Turismo 1 2 & 4. Still play them. Currently i'm trying to get through Doom 3, which is not an easy task as I can only handle 1 hour at a time. Maybe less. Medal of honor has been a favorite aswell, the latest 'airborne' looks awesome, though I haven't played it as my computer won't allow.
Wipeout 3 is another classic too.
