Don't forget the moeness of the girls. That's just pretty much of what every VN has: comedy, drama, moe and action if it's a chuuni.
I've never understood why people like comedy so much. I hate everything that makes me laugh or tries to make me laugh. It's such a waste and it adds nothing important to our lives. I never care if the comedy is good or not, unless it's the type of comedy not to make you laugh, but to relax you and melt your heart (like non non biyori comedy). And to make things worse, people IRL joke way too much. You can't run away. (There's comedy in fiction and IRL)
I usually don't care if common routes are good or bad, since they have too much comedy, anyway.
