I love all fighting games, but the only ones I've ever gotten good at are Tekken and Soul Calibur.

Unfortunately I peaked some time ago. I blew a lot of money in the arcades playing Tekken 5 and Soul Calibur 2, but subsequent sequels have just added more and more (and in SC5's case - killed off my favourite character) and it's been tough to keep at it. Tag 2 feels quite foreign to me because I was kind of slow to take up T6.
