I recenty started playing this game on PC, (originaly played it on ps2 when it was new) and it's still a really fun game, the gameplay holds up and even the graphics aren't THAT outdated, could just need some new textures. The game also scales(?- it fits my screen) unlike some other old games. Besides loadtimes are almost non-excistent.
I think a downloadable sequel would be a good fit for this kind of game (xbla/psn). Or a HD rerelease, its even got 4 player co-op! (wich supposedly is popular these days)
Heres how it looks on my pc, pretty good for a 2005 game. (jpg compression makes it look more grimy than it is)
