I wouldn't be adverse to No Smash for once, but at the same time, feels like the game is generally a staple in these kinds of things *shrugs*
We could just go and do SSB64, since we didn't play that at either con, but then, that game feels so dated compared to Melee/Brawl, so I dunno; feels like one of Melee or Brawl should be in. I'd rather play Melee than Brawl+, mostly cause people are familiar with Melee, and Brawl+ didn't exactly enhance Brawl for me, so if we wanted "Faster gameplay", I'd just prefer going with Melee rather than an altered Brawl.
With regards to Dissidia...
If people don't mind seeing only half of the match (or rather, the fight from one person's perspective, cause you can see a good deal of the match from one perspective), then we wouldn't need twice the TVs. That doesn't rule out the factors I mentioned above, the big one being 2 people unfamiliar with the game can make matches take forever. Again, Dissidia is not a "Pick up and play" friendly game; you need actual experience with it to find it enjoyable, and its system takes time to learn. This is fine for casual purposes, but for a tourney, it'll probably have the reaction Ciato had, even if the game is stylish as hell.
Also, I do want to say this:
I am against both MvC2 and TvC being in the same tourney. Now, what I mean is, having one or the other is fine; having both? Not so much. Its the same basic fighting game style, so yeah. I'd prefer variety in the Tournaments.
Which we choose, I'm pretty benign too; thinking MvC2 might be better on grounds of familiarity, both with the character recognizability (Marvel Characters vs. Random Anime Characters that made people think the game might not be localized, gee, I wonder!), which matters for novelty mainly, and just for familiarity with the game itself; I'm sure more people know how MvC2 functions and how characters play contrast to TvC.
That, and MvC2 has the REAL Mega Man, not the MML version that only a select few DLers care about <.< Then again, TvC has a lack of Resident Evil Jill <_< >_>
Edit: Oh yeah, one more thing...
We need not be entirely Fighting games. I'm sure having some form of Mario Kart in the mix, even doing it 4 player style if only to speed ti up (how we determine who moves on, whether its "Winner only" or do a round robin point allocation, hard to say) might not be a bad idea, if only for varieties sake.
That reminds me, an alternative way to handle Smash:
Do 4 player matches in earlier rounds. It'd make for a new take on the same game, rather than the same old 1v1. At least this way, people can have the aspect of Politics and general insanity applied in some manner. You don't have to play based on STANDARD TOURNEY RULE PLAY after all. Depending on style of Moving on, be it single elim, double elim, point style, etc, this could take longer, shorter, or same amount of time but just be more psychotic and amusing to watch <.<
