To me, an iconic moment in gaming is that moment when you're playing Jet Set Radio (or any game, really), and you pull that, like, really cool wallride to jump to grind to tricky-thingy to wallride again and just get that rush, you know? Like, your entire body gets all tingly and you're just, like, totally absorbed in the moment. Like pulling a really, really good drift in NFSU, or reaching the 2 million point mark for one trick combination in THPS2 without cheats. Or in Resident Evil (the original), the first time you ever played it, and you never knew exactly what was waiting around the corner, but you knew from the sounds that you weren't gonna like it.
