well, I just started playing some more UT2k3...mostly as a diversion, as it's *kinda* fun online, but god damn, 1942 is just too f'n cool.
anyway, 2k3 is spazzy DM action, and sometimes, that's exactly what you want to play. for that, it's ideal. 2k4 looks a lot like it's gonna try to be 1942 In Space, which can't POSSIBLY be a bad thing.
well okay, it CAN be, but they'd hafta try very very hard to fuck it up to the point of it not being fun.
