I'm an admitted Tribes fanboy too. I play anything else and I'm just sitting there thinking "Why can't I fly? Why can't I ski? Why ain't I playing Tribes where I can fly & ski?"
Tribes to me = incredible freedom and speed in objective oriented competition
Everything else = two dimensional fragfest - run/shoot/die repeat
So all my gaming interest is tied up in T:V being good. From what I've seen and heard, I'm excited. My only complaint is some of the stuff looks too dark & murky like T2. Admittedly this is probably mood setting for the single player, but it gets depressing for multiplayer. Hopefully multi will be brighter.
