OK, that's dumb, GW. You need to re-thunk that.
Games Workshop does more to themselves to insure their permanent obscurity than their competitors ever could.
GW seems to be reading from the T$R playbook from way back in the day. Not smart.
Microsoft and Bungie have "endured" some of the worst fan films (on YouTube no less) than anything I could imagine involving 40k... because they understand that it propagates the brand by viral entertainment. I think I'll be scarred forever by the Halo Kitty... but I own everything Halo that you could possibly imagine (and some you can't) including the Halo 3 Zune.
Strike out for GW.
