Well, what costumes do you have down right now? In my opinion, there should be effects for each costume, like powering up a certain type of Pokemon or causing eggs to hatch faster. I could come up with costume ideas, I'm sure. So then, what did you have in mind? Also, will you or will you not implement a seasonal system? I think that would be amazing honestly.
Oh yeah, and your thread still refers to me as Pkmnruler13. Would you mind changing it to Sheogorath?
