how many characters are playable?
Do they all have their own storyline mode?
Who is the main boss for evil? good?
Do fighting styles get to be involved?
will every character be seen? Fought?
Will test your might/sight, motor kombat, chess, puzzle kombat be involved for either challenges to get answers, extras, armor, weapons, money, etc?
Will you see characters evolve or devolve such as Reptile going through his bizarre changes?
Can you choose to be good or evil or by the choices you make in teh game determine your outcome?
Air kombat? Combo breakers? Parry?
Death traps?
What kind of finishers will you have? will you have the shaolin monks style, da/deception style, kaf?
How many specials will everyone be able to unlock? Does it stop there or can you additionally add to it?
What kind of surroundings can we expect to see? Jungles? alleyways? battle arenas?

I know these are a lot of questions, but i figure it will hlep out in determining this game for yah. Great Idea by the way.
