Nuzlocke! I'm working my way through X and Y and enjoying it quite a bit, but I'm going to put a project on the backburner for when I finish.

I don't think I've ever seen a nuzlocke through to the end, but I'm going to try. In fact, I'm also going to try roping in a friend who moved away and can't afford x/y due to being a poor student.

What's the best game to nuzlocke? I don't want something easy, but I don't want something so hard I'll cry. Or maybe I do, I don't know. You choose game, starter, and any additional rules.

Awaiting your suggestions!
