I just got back from the Shaymin pokemon event at GAME since it was around my town. I was scared I would be the only "grown up" there, but there were a few in their 30s there, all talking and battling with a few kids and their hacked, shiny pokemon.

I didn't do much there to be honest, all I did was download a Shaymin onto both my games, then went to the union room. There were a couple there but most left while I talked to them.
As for battling, I wasn't able to since my team are level 58, and unlike Battle Revolution, doesnt have a lvl 50-100 all to even the levels.

Anyway it wasn't bad getting a legitimate Shaymin, especially as the OT is MOVIE11. Hopefully the movie will come out soon then. Uh... thats all, hehe ^.=.^
