I just got the game. After two hours or so, it's exactly what I would define as "pure fanservice", with a dash of hack'n'slash, a bit on the boring side, with wonky camera. That's not too bad, but I've never played G.U. so I'm going to feel unfamiliar when I get to that part. Anyway, the story looks terribly fanfiction-y and the main character is an idiot. I'll play some more to see how it goes, besides, I definitely want to at least get some characters.
