Wow guys these costumes all sound really great! My first blizzcon was last year and for those of you who did Cosplay I just have to say thank you. It was AWESOME! Also, I probably have pictures of you haha.
I have been inspired to cosplay as my favorite blizzard character of all time.
This will be my first cosplay so I am sure it won't be nearly good enough to enter the competition haha.
Just because it is your first time doesn't mean it won't be good! Start a thread when you begin working on your costume and ask for pointers and such. Sounds pretty cool to me, especially since the majority of people who dress up for the con go with something from one of the new expansions or from D3 - would be cool to see more from one of the older games.
As far as the newer games are concerned, I think it would be funny to see someone dress up as a teddy bear from Whimsyshire with a sign on a pole displaying the loading screen that says at the bottom "There is no cow level."
