Are you that naive?
You KNOW that Hanzo and Fuuma are direct rips of Ryu and Ken.
I suppose you don't remember when FF:S came out, because it was a very surreal experience to play CE and then go play the SNK version of the same game(albeit with a better combo system).
WTF you don't remember? Naive? Condescending fat fuck, I'm just stating how things are. Hanzo & Fumma are to Ken & Ryu like many other ripp offs out there and yet you see no body giving shit to the companies for doing this, however when it comes to fighting games everyone is quick to jump the gun and call everything a SF ripp off.
Hanzo and Kumma are player 1 and 2 just like Ryu and Ken were back in the day, just like Ralf and Clark, just like Mad Dog and Scorpion and so on. Way before SF there was games that used the Blue and Red schemes for players 1 and 2.
I guess trying to have a discuccion with you is fucking useless 'cause you always want to be an asshole, is it because you suck at life or something? Try and be decent for a change douchebbag.
Note: Of course there's always the moves which are extremely similar, but you still don't get the point you oblivious fuck.
