Depends on whether we're talking 'shock' scares - sudden loud noises, unexpected foes etc - which any game can do, or overall atmosphere. Bioshock or Call of Cthulhu have the best disturbing atmospheres in my book. But you certainly don't have to be an A-list game to be tense and dramatic.
FTL and Dwarf Fortress certainly have their moments. FTL - low on fuel, with heavy hull damage, fires on board and not enough crew to cope with the hull breach steadily sucking all your air out into the void. One bad call and you're toast.
Dwarf Fortress - Oh no. An ettin. Will the dwarves survive its assault, what with them being ill-equipped, poorly trained and deeply resistant to doing anything to help ? Quick ! Muster the guards...oh hold on they've all gone for a beer...and to look at some statues. And to eat.
Uh oh.
