I've always kind of maintained the belief that I was pretty decent at Mariokart, particularly on DS - I can beat almost all of the staff times, which took me quite a while and it's not very often that I lose a race, so I figured I'd have a quick look around on the net and see how fast some people are - that's when i found this monstrosity:
Mariokart DS World RecordsI'm at the point where, even with snaking I seem to be going as fast as physically possible on a perfect line with every shortcut exploited, I really thought I was doing well, but good lord have I been humbled...
If you've ever been a fan of Mariokart then have a look at these times and be humiliated, some of these guys are clear of my track times by 10-15 seconds or even more and their peak individual lap times put every player I've ever seen to shame.
It's really impressive stuff.
