I actually like the art style but I'm not so sure how it will translate over to an arena type game. My initial reaction was that it would make things difficult to identify in a fast paced action type game, and that it might make it hard to allow maps and arenas to have their own sort of identifying features.
Ahhh, so this is that arena shooter that Jaffe said he wanted to make all those years ago. Hope it has server browsers like the last Twisted Metal, dude.
