Yea fightsticks are an interesting breed of controller. In my opinion, it makes playing games such as SF4 and MK9 feel nostalgic and fun! I kinda want to get one for my Wii to try Smash on it but if it runs at the same price as the other two (MVC3 $150, MK9 $180) I may have to wait.
But getting back on topic, I remember some of the new people were complaining about the headsets because, as previously stated by MasterP, it gives an unfair advantage to people who dont have them. Someone gave me the example of being able to hear footsteps behind a person in COD4 or the firing of a silenced pistol (which should not be possible without headsets).
