The cool thing about SF2 is that you can pick up and play with almost anyone and they'll have a favorite character and know the special moves. In my neck of the woods, SF2 was one of the three games that absolutely every single kid (girls included) knew how to play (the other two being Super Mario Brothers and Super Mario Kart).
It's important to pass the torch on to whatever this current generation of smartphone zombies are. I've met teenagers who haven't seen Fight Club...now that's scary.
