I'm still not convinced on Street Fighter. At all.
I have Super Street Fighter 2 for genesis, and tried playing it again, and it just seems like a so-so fighter. I found it kinda frustrating getting any special moves (aside from HADOKEN and HYUPCHYUPCHYUPCHUN) to work and I don't really see the longevity of the series. True, I was playing by myself, so maybe it's much more fun in multi player, but I'd still need convincing before I buy it.
However, prospect of online OCR matches is very appealing...
