It depends what kind of fighting game that it is, for
example:
If it was a fantasy fighting game like Dragon Ball, which
combines martial arts & magic attacks then you could call it,
"Mortal Fantasy Fighters."
If it was a game which included backstreet fights & the use
of weapons, then you could call it, "brick busters."
I hope this helped if you tell me what kind of fighting game it
is I will do you a personal fighting game title!
