I don't know, Little Busters isn't super ORIGINAL with anything it does, but something about it really resonated with me, both when I first played it and now. Granted this is coming from a huge Key fan, but I genuinely think Little Busters is their best work, even if it does have some flaws. Also, on topic, I would agree that even though I liked Clannad, the ending was a complete asspull. I think Little Busters pulled it off a little more susuccessfully, though.
