I like the Moose hat idea. Or maybe a penguin suit (which I am sure does not fit the feel of the game ... but pegnuins rock).
I have to add here that I feel like their biggest error in this entire process was their technical support. I had major errors beginning the game, and the solution to my problem was not on the website. My husband helped me to fix it, but it left me with an extremely bad taste in my mouth. If they had gone through the effort to at least document many of the problems on the official site (apparently mine was actually a major issue in beta), I may have given the game more of a chance. As it stands, they have lost my business. The official support site was decidedly poor. Very small and incomplete.
OK, I am done with my complaint. I expect problems with the launch of an MMO, but there is something to be said for at least recognizing that they exist and attempting to provide folks with a way to fix them. I really don't like to be the grumpy customer.
If you had a GOOD experience with a problem from AOC, I would like to hear it to regain my faith in the folks in charge of this game.
