Guess? Literally made him my avatar
lol I started as a Ryu main literally only because Daigo used him, but then I branched out as I learned the game and picked up stronger fundamentals. Shotos are still my home-base, my comfort food, but I eventually got kinda good with Gen in SF4 (definitely my weirdest pick-up, and I had to sink a ton of hours into Gen combos to get even average with them).
In USF4 the chars I was good with: Ryu, Ken, and basically any char that used shoto archtype. If I wanted to troll online I'd use Evil Ryu and do ambiguous dive kicks on knockdown, lather-rinse-repeat.
Chars I was "ok" with: Gen, Yang, Balrog, Chun-li.
I got burned out on Street Fighter because of how lame SF5 is; though I still sunk almost 700 hours into it before finally dropping it for good. Only char I bothered using there was Ryu and never bothered experimenting with any others because they are all equally boring.
Sometimes I still fire up SF4 just to practice 1-frame links for fun, reminds me of practising scales on a music instrument, though honestly I'm really rusty on any FG. Haven't played a FG in almost a year now. In some ways it was a good thing because I just go full-retard when I get addicted to something, and I never experienced an addiction as STRONG as when I got addicted to SF4, to the detriment of almost everything else.
