I personally think that Street Fighter IV: CE and Soul Calibur are the best android fighting games that are currently available. Does anybody have any other titles, which they would like to suggest?
I don't know, are you looking strictly for fighting games in the style of Street Fighter, or for any game involving combat, the use of special skills etc? I'll look into the latter (I know a colleague who plays one, but I have to ask him what it is) and for the former, I'm playing Azur Lane and I'm having a blast.
So far I've only ever tried Injustice and Shadow Fight 3. They're definitely good. Not sure if BlazBlue is still being update but yea you can check them out on PlayStore.
