I hate the training in GSC so much, I could never do a rotation team...like...ever. :< At this very moment, I'm hunting a shiny Petilil in both my copies of White. Running in the grass on Japanese White and hatching eggs on English White. I'm crazy, yes. But it's like...my favorite Pokemon. I WANT THE SHINY. I'm over 1000 eggs too. :<
You should play Vietnamese Crystal. It's the greatest game ever, with the elf's world.
