Me, Havak and Retro 0range went to the Trafford event yesterday afternoon. There was pretty much nothing there except the download terminal and some DS' with diamond and pearl in. As a practical joke, Retro 0range traded all of the pokemon from the display game and replaced them with 6 bidoof and starly nicknamed:
I
Stole
Your
Pokemon
Nintendo
HAHAHA
Good times. I think he got another event shaymin from the cart too. Apart from that we spoke to and battled a few guys from other sites, andthere was a creepy old guy talking about how he wanted flying pokemon to be immune to thunder when rain dance was in effect (I don't know). There wasn't a great deal to do there but it was a fun day out regardless.
No sign of Toothache this time. Dunno if you went, we probably missed you because we got there quite late.
I can confirm that the event doesn't work with US versions of platinum. You get an error saying something like
"This event is not compatible with this version of the game"
Sorry Jhonny and anybody else who was using platinum. My friend who was going to the Sheffield event is in the same situation.
