I'm willing to wait pretty long amounts of time IE I played though Ever 17 despite being completely bored 80% of the time because that last 20% was so incredible it made the other 80% worth it.
Isn't it based upon a VN series of games? Does playing the game/s first help explain whats going on?
Fate/Zero is a prequel to Fate/Stay Night which is a VN. F/Z is an LN and the show is an adaptation of it. F/Z is however 10000000000000000x better than F/SN. Avoid F/SN altogether and just watch F/Z.
