I'm the first person to attempt runs of many categories for the game "ModNation Racers!" I find it really cool to be able to come up with categories, routes, etc for games. Feel free to check out some of the runs if you like! (So far I only have a run in the category "Home Tour"). http://www.speedrun.com/mnr

I agree. It can be daunting though depending on the game, and not having competition may burn you out quicker than you anticipated.
