For Horror, Silent Hills. If they haven't been put up there yet.
For RPGs, I'd suggest Shadow Hearts and Final Fantasies. But that depends... Shadow Hearts is a fairly short game, and FF's are NOTORIOUS for being long. It also depends on your play-type. (IE: if you look in Every possible room for something/anything.) But I've never played Baldur's Gate. :| So I really don't know how that is.
