Without a doubt:
Sequel (of a beloved game) - There have been few sequels to a favorite series of mine that have not satisfied me. They do not even have to surmount their predecessors, they just need to entertain me (and for the most part they always do)
New IP - These can easily defeat the two above (this gen Demon's Souls for instance) but they have a much greater chance than the above 2 at disappointing me.
