I first saw SC as any other fighting game when I was so young, but starting to realize it's a different genre, unlike Street Fighter and Mortal Kombat where people bottom mash. I started by playing SC2, got a bit into it but than SC3 came out and I starting to like the series. SCIV was alright but not thrill though.
Yeah he's my main and favorite also in SC2, because the move set is perfect, his weapon custom, his tap dance and in SCIV and SCV he doesn't feel the same. Amy is my main and favorite in SCIII and IV, because she reminds me how good Raphael was.
