Why is SF4 selling better for PS3 than 360? Is it that Ps3 owners are older and hence the SF nostalgia?

Japanese loves Street Fighter 4.

As you see, the PS3 sells way more in Japan than the 360, therefore more copies of SF4 and being sold in Japan making a difference.

Also, SF4 is a classic which PS3 owners like.

Not being a fanboy, but most 360 owners do prefer shooters.

It's probably more that the D-pad on the Xbox controller is really bad so the game is easier to control on the PS3 than on the 360.

Maybe it's because PS3 won the tournament

or

There's still Street Fighter fans in the PS3

Who knows.

because it has better japan sells and others sales 360 is just american market
