Several different girl gaming networks and groups have pulled together a mass of games from different sites, forums, and other networks devoted to female gamers, and have put together this list of the final nominees. While they encourage female gamers to log in and vote, it doesn't look like they'll be screening for X or Y chromosomes at login.
We've recently been talking about developing and marketing games for females, and this is a great example of how to do that -- find out what they're playing, not tell them what they should be playing. However, in all honesty ... this looks like a list of games that could have been pulled together from sites populated by only male gamers. Further proving that the line between girl gamers and guy gamers is something created by PR and marketing, not the people who play the games.
Our advice? Open up the voting to everyone, but have them identify which sex they are (Austin Powers: "Yes, please!) from the outset. Once the awards are done, give us the winners, and show us how the demographics break down by sex, age, toothbrush color, favorite type of pizza, etc. That way the marketers will see we're all just playing games.
