I am based i the UK and I have preordered 2 copies of GWEN online - 1 from game.com and 1 from Gameplay - both a bargain £17.99.
Anyway, when i did this with Factions, they emailed me a code whcih I added to my account and gained access to the prerelease. Obviously later on release date I received the actual game.
However neither company has sent me a code this time

If anyone could help me on this i'd be greatful as i have emailed them and received no response!
Best wishes to you all
