For me it has to be Conkers Bad Fur Day 2. The original is still by far my favorite game of all time. I beat it multiple times put hours into the awesome multiplayer. I read what the 2nd one was going to be about and it sounded like a good idea. That game is the only game that would make me buy a non Nintendo platform...Oh Nintendo how could you sell Rare?... Anyway what canceled game devastated you the most?

Silent Hills! Looked sooo damn amazing!!! God damn it Konami T_T

The unfinished 3D Pokemon RPG on the N64 and PT

Silent Hills.

I was kinda bummed about Megaman Legends 3. I loved the first two games. Cracom sucks.

Jak 4.

Silent Hills. I know PT was not indicative of the final product but goddamn , my hype was real.

Megaman for the 3DS.

Last game we got was Black Ace(which wasn't amazing, but still fun to play).

I really just want another megaman game. Seeing him dead in Smash(in terms of online) always reminds me of the 5+ years without a megaman game; really bums me out.

Mother 3 N64, if only to know what exactly it would've been like.

Probably Silent Hills. I was long awaiting for a series revival and after playing P.T I was pretty confident about the future of the series. Oh, well... =/
