Conquest. Just going through the side stories. Got a lot of the legendaries like Registeel, Dialga, Mewtwo, Terrakion, Zekrom, and Reshiram and I have most of the perfect links and the warlord transformations, but trying to get the other people is annoying when I can't find them.
Why do people... betray one another? They might as well... all just die instead. Welcome to my kingdom!
Working on finishing off Sinnoh Beauty ribbons for my Shiny Cloyster (obtained as a shiny Shellder in Pokémon XD, two weeks ago). Already got it the Hoenn Beauty ribbons, and managed to get it the pretty Earth ribbon too.
At the same time, working on my seasonal replaying of Pokémon Channel. Each holiday season I play Hey You, Pikachu! and Pokémon Channel (for Christmas nostalgia).
If I have time before NYE, I will probably replay PokéPark Wii. The Iceberg Zone is gorgeous!
