No your not a bad person. Lots of people like porn. Because thats what it is. Porn. Most video game contain a good deal of male-oriented porn. And if your okay with the industry being capable of aspiring to nothing more then porn, then you're fine. If you fine with every goddamn action game in the universe trying to throw in porn as a feature, then you are the current ideal demographic. But if you think that there should be a few games that are NOT porn, then maybe theres a problem here. Personally, I'd like to, every once in a while, have female character that I can interact with that I don't feel like the creators want me to masturbate to. For variety sake, if anything.
Personally, even in my porn, I prefer human women, and not creepy, alien, chest-based flesh-mountains.
