GameInformer has a poll running now until November 30 that you can vote on daily for the Top 30 Game Characters of the Decade. I'm not sure how they compiled their shortlist (Example from Street Fighter IV: Why C. Viper and Seth but not El Fuerte and Rufus?) but at least they have left an open field for any characters you think they missed.

Here were my choices:

1. Gouken (SFIV)
2. GLaDOS (Portal)
3. Amaterasu (Okami)
4. Alyx Vance (Half-Life 2)
5. Kratos (God of War)
6. Andrew Ryan (Bioshock)
7. Scott Pilgrim (Scott Pilgrim)
8. Meat Boy (Meat Boy)
9. Patapon (Patapon)
10. Locoroco (Locoroco)

Additional character: Biggs (Critter Crunch)

I recognize that my choices are probably far off the mark from what will end up being the most popular choices. (I totally bombed the GameSpot Greatest Hero and Greatest Villain brackets because I chose my favourite characters over who I thought might actually win.) I also didn't spend a lot of time debating why I made the choices I made. I think I based it on how excited I felt when I read each name. Several names I didn't even recognize. For example, who the hell is Dr. Derek Stiles!?

Patapon and Locoroco were total throwaway votes... I just didn't know who else to put in there and they're visually distinctive.

Crap. I should have included Lei Fei!

At least I can vote again.
