To explain: in Street Fighter 2, there are six buttons for hitting people. You can press them while you're standing still, ducking, jumping straight up in the air or jumping forwards and backwards. Then you've got two or three special moves, but they're fairly easy to learn. After one glance at the move list, you can literally do any of your character's moves any time you like.
By contrast, Tekken and Virtua Fighter take ages to learn. Every character has about fifty very specific combos, along with twenty special moves that usually aren't at all memorable. It'll take you a good few hours just to learn them all, and then you'll probably forget half of them the first time you need them.
If you're not acquainted with boxing or (more likely) jujitsu, here's how they work. In boxing, you've got about six punches - jab, straight, left and right hooks, left and right uppercuts. You can do them while you're ducking and moving and stuff, but that's about it. Throw in some rolls to the side - which I'm not very good at - and some blocks, and you know how to box. What you don't know, obviously, is the infinite number of ways you can combine all of those things to make combos and flow from one move to another and distract the other person from what you're really trying to do and set up the thing you actually want to hit them with.
In BJJ, by contrast, there are fucking loads of moves. Even if you discount the stupid ones that nobody ever does in a really serious fight, you need to learn to do about twenty things really well before you'll stand even a vague chance in a BJJ match against, say, a blue belt. Then chances are he'll still pull something out of the bag and armbar you anyway.
I don't know why I bring this up. I just think it's interesting.
Look here's a picture of Guile:
I BLOODY LOVE YOU, JANE.
