I liked it a lot - even more than Friendsim, in fact, which I didn't expect. It just has a really fresh take on the familiar characters. The fanserviceyness mainly takes the form of the Reader learning about each character's angsty pre-game situation and trying to help. So, it has the feel of the more melancholy Friendsm routes, though it's pretty damn funny in places too.

(The Epilogues connection only really comes up in the final chapter, which is Dirk's route and the ending.)
