I really liked FFS, I once owned it on Neo Geo. I honestly thought it was more balanced gameplay wise than the contemporary Street Fighter games. I definitely dug the backgrounds more and the music as well, over SF, but for some reason I just couldn't get good at FFS, not like I am at SF2 series.
I think I found FFS too late, I just couldn't concentrate and zone out enough to master all the different moves for all those characters. It's kind of tough to do that with different fighting games I think, unless that's all you play. I have the same problem with Kasumi Ninja and Ultra Vortek on the Jag. I love both those games, but I had already mastered MK1 and it makes it difficult and time consuming to master all those new characters, unless I decide I want to just play those two games exclusively for awhile, but I don't see that happening. I'm not sure I have the capacity to memorize all that stuff nowadays.
