Final Fantasy Dissidia
I stumbled on videos of it through random YouTube surfing, I'm not a big fan of fighting games, nor of the fact that the gameplay changed so much, but I'm still a fan of pre-X FF, and seeing characters from the games just makes me itch to get it. I didn't because I know my attention span for fighting games last for ten minutes, but doesn't stop me to actually consider getting it.
Fatal Frame 2
Everytime someone asks which is the scariest game, or anything about Amnesia: The Dark Descent, I just want to replay Fatal Frame 2 (my favourite scary games if you haven't realise by now), not to mention the urge to argue that Amnesia is inferior to my FF2 (<- really devoted fan speaking). Sadly, I no longer have my Xbox, nor do I have an 360 (or knowing whether a Xbox FF2 works on a 360 or not).
