I will say this in his defense, he could not like female protag games for the same reason I don't(though I still give them a try). That reason being that 90%(made up number because I haven't played anywhere near all of them) of them consist of a female protag that is blackmailed/raped by the stupidest means ever seen. I keep looking for some(and have seen one or two) where the female protag isn't a complete idiot.
Yeah kind of ruins the appeal for most female protag games for me and probably most people - especially if you want to try one to change it up a bit - when the only scenarios for a female MC game are:
A) Hmm I've been blackmailed by my 400lb boss or some completely nerdy guy. Guess I need to spread em!
B) I used to make smart choices and decisions in my life. Now I should do the opposite and get myself in all sorts of precarious and idiotic situations.
OR
C) Just raped. No reason - just throw rape and non consenting gangbangs in there for some reason. Because... plot progression you say?
I mean take any of the popular games out there or well received games (ie Depraved Awakening, Acting Lessons, hell role reverse games and scenarios with a female MC for games like Melody, Become a Rockstar, or Where the Heart Is, etc) and flip the story with a female MC and I'm sure people would enjoy that more than most of the female protag games out there.
