I actually read an interesting blog from an auto show booth babe and it was kinda interesting. The main difference is the video game booth babes know nothing and don't care about the product. A lot of the auto show gals actually know an awful lot about the product. The blog has a lot of fun anecdotes about this girl utterly schooling a bunch of guys on basic auto knowledge when they tried to get all macho with her and throw some lameass pickup line. Also the auto show gals aren't as ridiculously underclothed. It's generally short skirts, tight dresses and such...but they all know the cars inside and out. The game show ones I think generally are utterly clueless about the product and are just there to make a buck and deal with crap.
I have a couple general questions about this. First I don't think sexy is inherently a bad thing. I don't think we need to start some crusade against bare mid-rifts and I think a larger issue is a sexy character is often only defined by being sexy. When you make a female character sexy and in revealing clothing they pass on any other character development and leave her as the 'sexy' archetype. Which isn't really a character at all. I think there's a few good examples of a character who wears revealing clothing or is sexy, but also is a fully realized and developed character so when you're asked "Oh? What is that character like?" The answer isn't solely "Oh, she's hot." I'll offer Morrigan from Dragon Age and Chloe from Uncharted 2 as sexy characters that are more than just looks. Morrigan actually has a full background and even a reason for dressing the way she does. If you ask someone about Morrigan your'e sure to get a laundry list of what they thought of the character and motives. She was in revealing clothing, but she was also a fully realized and well written character. Chloe is the same way. She's not in as revealing of clothing but has a sexy attitude, but also again...is a fully realized character in that world.
I think the argument is a bit less "Cover the girls up" but "Make them have reasons, motives and traits like any other character should." If they're wearing revealing clothing? We should know why, and the reason can't be "Oh, she's the sexy one."
Similarly in a game where the players have a bit more control on what their main character is I wonder about that. Like, lets look at TERA. The female character armor is ridiculous. ..however, the male armor is ridiculous too. They show a ton of skin. The gals show more I think? But it's not a case of heavily armored guys and skimpy girls. It's skimpy guys and skimpier girls. It's an aesthetic to the game. It's extremely polarizing but it's consistent. Now I agree there no options in the game if you want to be covered up or armored, and a lack of choices is generically bad so players can't be what they want to be, but is it sexist in this context? EVERYTHING is sexualized and objectified. Where does this fall on the scale? Is it more okay if the guys are just as sexualized/objectified or is it more bothersome if it's a gal character is and the male character is not?
