Personally I play both PS2 and PC games. I much prefer PS2 games for the
action or fast paced games. I feel they are more built for this. Unless ya
wanna spend alot of cash and get one heck of a pc. But I much prefer PC for
on-line games. I've tried PS2 on-line games and found them rather limited.
Since you are limited by upgrades and expansion sets. I can't see myself
playing the same game for years without much for an upgrade.
I doubt that console will take over PC in the aspect that there isn't
expansions, just sequals to the same games.
I personally prefer the PC for its flexibility, however it does need
to constantly be upgraded to even be able to play certain new games
(e.g. Halo, Doom 3). All in all, I suppose it is up to whether on not
you care more about your system or the fun you get out of it!
