For me in terms of pure disappointment, Euraka 7: AO wins by a land slide. Doesn't deserve the "euraka 7" part of the title >_>
As for SAO, I had already read the novels, so i knew exactly how everyone would react to the 2nd half :P Nise would have to come 2nd, but for the fact one already knew Nise was the weakest book in the series, so expectations weren't that high from the get go.
I'd say Little busters for second, considering its a Key work, and I've already dropped it
