Aye, my brother and I (God, we must have been 11 and 8 at the time) used to play this endlessly. Timing ourselves and trying to beat our highscores/times on hard over and over. So many good memories coming back playing through it, had to laugh ending up #3 on the leaderboards after my "for fun" playthrough on normal. We really did play this one a bit too much.
Recon it will be getting brought out time and time again when I'm bored for a bit. Be fun to see if I can ever manage the 100 minute Timeron challenge. Now *that* would have been a better achievement!
