Tetris Attack (NO, 4, 4, NO)
Smash Games
Melee (5, 2, 2, 1, 2, 1)
Brawl (2, 2, 1, 4, 1)
Smash64 (2, 2, 1, 1)

Other 2D fighters
Melty Blood (1, 5, 1, 5, 2, 5)
Blazblue (4, 1, NO, 3, 1, NO)
Guilty Gear (5)
Other...whatever it is
Dissidia (5)
Double-Dash (4)
SMB3 vs. (4)
Definitely in: Melty Blood (most-demanded), some form of smash (also most demanded)
Very likely out: Puzzle games, Dissidia, SF4, Guilty Gear (just...not seeing heavy support).
Maybes:
MvC2 (4, 3, 3, 3, 2)
Tekken6 (3, 5, 2, 1)
SF2HD (3, 3)
Blazblue (4, 1, NO, 3, 1, NO)
TvC (4, 3)
SC1/2 (1, 3)
SMB3 vs. (4) (Only has one support, but damnit 30 second matches, everyone knows it, surprisingly good for spectators; I'm not inclined to rule it out just yet).
I....what? Please specify
Double Dash.
In particular, how would we play that like a fighting game? What mode? What setting?
Aaaand...the big surprises for me here are that Tekken 6 which we've barely talked about actually has a lot of demand, and that more people want Melee. Let's put asside the "which smash" discussion for a bit...
Questions:
Assuming Melty Blood and some kind of Smash are in. In this event is it better to have Tekken (for the 3D fighter) or MvC2 (for the whacky). Or a third option that's getting attention (SF2, Blazblue, TvC, SC).
Tekken is a pretty short game, and 2v2 Smash frees up a lot of time. It's possible we will have enough time for both Tekken and MvC2 within the budget (I will have to calculate). Would people prefer running both matches with corners cut in each (2 stock for Tekken, time limit in MvC2) or would they rather run one of the games longer?
