First of all, I want to clarify something about this post: SolLock's Log isn't going away. It's just going on hiatus for a while.
I'm planning to play Pokémon Y as a Nuzlocke challenge. I was hoping to beat the Elite 4 in Pokémon X first, but I don't want to miss out on the free Torchic with Blazikenite in either game, so I'll have to start Y and get far enough into it to Mystery Gift to get that, and I'll have to do so before January 14th.
Once I get that established, I think that I'll actually resume my Soul Silver run before my Y run, before I get too accustomed to these fancy new graphics, etc. In either case, though, I'll still try to do "whole" days, but my current focus is on Pokémon X, so there might not be anything substantial from either Nuzlocke challenge for a while.
