So I'm just about done with my FR Nuzlocke, just doing the mandatory grind before E4 because I recently lost a couple big hitters. I'm planning on going through all 5 Gens in order, taking new challenges to make them fun. Nuzlocke was cool, but really grindy.

What should my next challenge be? I can't really think of any other than either a type run or a starter only run.

Hell, if someone pitches crazy and fun enough rules and I'll document my travels through Jhoto and Kanto.
