Only played SC2 and I dont intend to play another, but SF has always been amazing, just really want it to come to the Wii now.

Soul Calibur 4 for me. I never reallly liked street fighter.

While I'm not about to make detailed comparisons between the two, I just like SoulCalibur 4 better due to having weapons as opposed to just fists, which is the reason while I don't really play any other fighting game besides the Soul Calibur series.

wait for a price drop, fighting game get boring after a couple days i would never pay full price for a fighting game.

Street Fighter 4.

Street Fighter is the only fighting series to me that has been able to with stand the test of time. It is still as popular as when it was first released. Not many fighting games series have been able to pull that off. Think longevity since two was the most popular of it's time Street Fighter has been getting action since 1992. No fighting game series can say I've been around 16 years. Heck, it's been around 21 years if you count the first one.
