Game would be a lot better if it gave you a choice whether or not to pursue the Nana route or not as it does with the other girls. I get it, she's the main poster character, but not everybody likes the old woman thing. That's usually the draw of games like this with a ridiculous number of diverse female characters, there's something for everybody but gives you the choice to only pursue the ones you like.
I like this game because a bunch of the girls are great, but don't really like that old lady bits being shoved front & center without a choice about it. Unpopular opinion perhaps, don't know how many people here like Nana, but she's the reason I'm kinda on the fence about this game. Just saying it would be a lot better, at least for me, if it let you choose whether or not to be on her route and see her scenes when that choice is given for pretty much every other girl.
