I'll say Final Fantasy. I loved every Final Fantasy released by Square until they merged with Enix (well, except 2, 3 and 11), but I've hated every release after the merge, except for 13 (and Dirge of Cerberus, but that doesn't really count), which has given me some hope. If they continue using all their old traditions again and get rid of that awful linearity, it could get good again and I will be very happy.
Also I'll throw in a predictable vote for Silent Hill. 1 gave me chills pretty often, 2 had me on edge the whole way through, I have yet to play 3, 4 scared the shit out of me, and... yeah. The only new one I've played is Homecoming, which I didn't mind as a game but it wasn't scary at all. Origins and Downpour don't look interesting to me either.
