I would have to say no. Toribash's physics engine seems to affect tori and uke differently. This would definitely disqualify it as a e-sports worthy game. You know, it's not a balanced/even game.
Like I said, the physics engine affects the players differently. That's what makes it uneven. Toribash doesn't have any in-game items that affects gameplay.
The differences are near negligible, you don't see people winning because they are either tori or uke... Ever. There are clear differences in skill levels, if you are better than someone else and you're playing a mod that isn't a gimmick, the chances are very good that you will beat them.
The only thing is that it would never really be all that exciting to someone who doesn't understand what is going on, so it probably will never take off.
Toribash lacks any original thought since conception (that is, the idea of a joints and forces based fighting game with a strong 3D physics engine is about as far as it goes), this makes it perfect for e-sports, which all, also lack any originally at all.
I'm involved with E-Sports. I play games like SC2, LoL, CS 1.6, all of them.
I think this game has potential to be an e-sports worthy game. Toribash is VERY complex and respectable in my opinion. The "Starcraft" of Fighting Games. The game requires the use of hotkeys, memory of inputs to execute proper moves and the game is exciting to watch (especially when a Toribash player pulls of a sick attack or counter).
Do you think Toribash is E-Sports worthy? If so, what can we do to show this game to more people? LoL was free to play and erupted! 5 million people playing it or something like that.
