chris100185: I think general opinion holds Street fighter II the highest.
You are wrong there. Street Fighter II was HORRIBLY unbalanced. You could not play the same character VS themselves. I could go on,but...
I'm torn between SF II: Champion Edition or Alpha 2.
I could never get in to SF III.
Oh and the arcade versions were ALWAYS superior. With the exception of Alpha 2 for the Dreamcast, all the console versions pretty much sucked.
