I play mostly on the 360, PS3, and PC. Though the PC has been getting the most action out of the three of late, and will get more with Street Fighter V and Killer Instinct coming out.
The PS4 and Xbox One are grossly dissapointing for fighters. My family keeps wondering when I will buy one, but how do you justify a system for one game a piece? Now that the PC is getting titles it's less then that for me.
