i haven't played the game, so i can't speak to the manner in which it's played...but i would suggest that "sexist" might be the wrong description for what's being portrayed here.
the reason i say that is because there are two characters in the commercial portrayed as female; one of whom is "cogitating", while the other thinks about "sparkly balls".
because the "-ism" in this ad is not as much directed at women generally as it is towards just the one character, i would suggest instead that, if anything, "blonde-ism" is what's at play in this circumstance.
all that said, i did recently make the acquaintance of someone who absolutely epitomizes the ad, which is why "sparkly balls, sparkly balls, i've got sparkly balls" makes me chuckle every time i hear it.
