The old school games are where it's at for me, the classics like 4, 1, 3, Bloodlines, Rondo, X68000, and so on. Although two of those, Rondo and 3, have branching paths, which I really like. That probably should have been its own option, but oh well.
SOTN is farkin' brilliant and up there with the best, but all of the other games in that style just don't compare, in my mind.
