A fighting game as in playing it ourselves like Street Fighter or Mortal Kombat? Or to bet on virtual fights between various animal characters with or without a fight we can actually see

Not a bet, an actual fighting game like Mortal Kombat.
I do not see the logic of a fighting game on the blockchain at this moment. What is the benefit of that? I get that with gambling since the blockchain makes it transparant and avoids scams.
How would you see a fighting game thats suits the blockchain technology? What is the benefit of a fighting game on the blockchain?
You'd be able to use the XBL tokens to purchase champions and hats, among other things.
Ok like that you mean.
Well personally I prefer (at least for the initial period of development) to focus on gambling games like the raffle, poker and some others (maybe wheel of fortune, blackjack). Otherwise it will be a few games of multiple categories while in my opinion it is better to initialy focus on something first before expanding your game types.
But that's just my opinion.
