Yeah, in my opinion as good as the game is, it just takes too long now to see all the paths/options, especially without a decent ingame Walkthough/cheating.
I do believe there's a point where a choice game, simply has too many options/choices.
Hell, I'm not even sure how many saves you'd need to see "all the paths" each updates at this point.
I mean, it's both good and bad to have such a massive game. If you want to stick to a single path, then you'll be fine.
But even two paths now is starting to be quite heavy to do. Problem being in a VN, that you can not have radically different things happen, you do need to maintain a common core until the ends usually, meaning the player will be forced to rewatch the same stuff over and over if there are many paths. It's a bit of a double edged blade.
