Street Fighter is literally one of the highest grossing games of all time. One of the games is even "Street Fighter X", involving Tekken (another mega game). CapCom would definitely protect their precious games. This domain is trouble, IMO
This looks like a trademark name but do have a check on Trademarkia. If yes, drop it. If not, this could be worth mid XXX to high XXX IMO.
Look for more opinion on this one.
