So we are like one month into the long wait for episode 10 and the topic is that there is too much porn in this game?!
Personally I think it's just about right.
I'm not interested in a college dating simulator, I want a no-holds-barred, raunchy college sex-comedy. Sure, the mc can have a girlfriend if he likes, but he can also aim to fuck as many women as he can before graduation!
The good news is you can play it either way, the nice guy with a girlfriend, or the party animal with multiple STDs.
And regarding what the girls are often wearing, it's just fan service. There's a fine line between what they are wearing actually meaning something (like Josy feeling a little exposed in the HOTs outfit) and the outfits being purely for our enjoyment and not of any consequence (like the way Bella dresses for work).
It's like how somethings are meant to be taken seriously (like Vinny pulling out a gun and hitting the mc in the face with it), while in other scenes Derek is flying through the air farting on a security guard to save the mc, and it works!
So girls walking around on campus one step away from naked, just enjoy it, that's why it was done.
