Rune Factory 3 had the best girls, Rune Factory 4's girls are all... pretty forgettable and lack in the crazy which would help make their personalities stand out more.
Also lacking, is tits. I mean, I swear, each fucking game they taunt me with the milfs and then to make things worse, none of the girls have a decent rack on them.
Another complaint about 4, can't marry the dragon. So disappointing.
