Game challenges you like to impose on yourself

[Kriven]

I've been slowly working through an Ike-only run of Path of Radiance for the past few years. I mean, I only pick it up every six months or so and complete a chapter, so I'm not very far at all, but it's a pretty fun challenge so far. I think I was level 20 by chapter six or seven... Been stuck on the same chapter for a while now because I was careless with my Vulneraries.

I sometimes speedrun Super Mario Bros. 2, if that counts.
