A lesbian is definitely going to bring a unique point of view to a review of a game. Sexual identity is an extremely large part of most video games, particularly those which are action oriented- if only because anything which deviates from the heterosexual hypermasculine norm is rendered invisible. I think it's easy for heterosexuals (and I include myself in this criticism) to forget that we don't have to call attention to our sexuality ("to make a big deal out of it" as some like to say) in our day to day lives because that sexuality is assumed to be the norm.

For instance there was a thread on Kotaku not long ago about a man who was forced to change his gamertag because it was "Gayergamer." A lot of the comments felt it was rediculous that the man felt the need to call attention to his sexuality. However, as others pointed out, heterosexuals do this all the time. However this is normative and so it doesn't really grab our attention. I've seen tons of gamertags on xboxlive expressing heterosexual virility and nobody bats an eye at those (myself included- doesn't really bother me), but as soon as a man dares to openly declare his homosexuality, the community is all up in arms.

I know that you weren't talking about xbox live or anything, but i just thought that served as a good example of how we often fail to recognize that heterosexuality is proclaimed as the right way, as the desirable way to live everyday- and it informs how we think and act so much that we often fail to recognize it's influence. Thus marginalized groups, such as lesbians, definitely have a unique take on things, especially video games, which have traditionally been a bastion of normative heterosexuality.
