Not sure how to respond to that. I guess it all comes down to how serious she was.
On the one hand, yes, Yahtzee uses way too many inappropriate references at times.
On the other hand, the review that he made the most in (Sims 3), to me, sounded like willful self-parody. It seemed like he was intentionally over-doing it to take the piss out of himself, and he even went on that whole "If you think you're funny when you're really etc. etc." rant in which he pretty much ripped into himself.
Also, was it intentional to make the singer look like Yahtzee's version of Lara Croft (same hair and color shirt I mean)? Because that's the last female game character any feminist should be standing up for. She's a poorly written cardboard cut-out of exploitation, who wears unnecessarily revealing clothes and is anatomically unfeasible. I mean her last game's box art didn't even show her face.
If you want to stand up for female video game characters there are a lot better ones than Lara Croft. Jennifer Mui from the first Mercenaries game, is my personal fav. She's incredibly smart, incredibly skilled, and best of all, the game doesn't make a big deal out of her being female. There's no stereotypes, no sexual references, no revealing outfits. She's a highly trained mercenary and that's how the game portrays her. Unfortunately the sequel kills her by making her talk about things like fashion and shopping and dressing her in skin tight pants (none of which the character in the first game would have done at all).
Another good one is Wynne from Dragon Age. It's not every game that has the guts to incorporate a strong-willed, out-spoken old woman, and then still portrays her as being a woman, talking about her love life and even flirting with Oghren. A very rare character. Though, to be honest they could have cut the jokes about her age in half.
