Kind of playing devil's advocate here since I'm generally more fond of Japanese games, but I'm a girl and I've never had a problem with Western art direction. I loved the visuals of the Baldur's Gate games and Planescape Torment, and The Witcher 2 is just about the most impressive looking game I've ever seen. It's true that I do tend toward softer, more cartoonish art, but my (also female) friend swears by a more realistic approach and swoons over the graphics of games like Uncharted and Mass Effect. So I'd be inclined to say it's less of a male-female thing and more one of personal taste.
Now if you're having a go at games for not presenting compelling female characters from a writing perspective a lot of the time, then there I'm with you. But it's something that's getting better and better. And I wouldn't say Western games are any more guilty of it than Japanese ones. Heck if nothing else, Western RPGs usually offer you the chance to play as a girl if you want to, as well as giving you some degree of control over her appearance and personality. Yes there are token bimbos in some Western games, but that's true of Japanese games too. Heck there are plenty of Japanese games that trade either heavily or completely on female sex appeal. Ar Tonelico 3, anyone?
Oh, and reading back on previous posts, was Uncharted being cited as a game that isn't really appealing to women? Really? I thought both Drake and Elena were fantastic, well-rounded leads that would appeal equally to those of both genders. And I had a pretty massive crush on Drake over the two games.
