It keeps striking me how this game's engine turned out to be a lot more complicated than the creators originally intended. Sure it's still quite limited and buggy as hell, but let's not forget this was supposed to be a game for kids.. just see how poor the SP is, even on hard mode. But within a few years, the community took it a few levels ahead.

I remember that in 2004 or so, before every important duel, I dug in levels trying to find little tactics that'd help me to win, and that was what it was all about. There was a lot of invention back then, and if you knew how to RF climb, you could've already beaten most players.. now of course it became one of the basics, and all those tactics I (among others) invented are just learnt quickly and used automatically by all players without much thinking.
