I'd have to nominate FTL: Faster Than Light (which is a tautology when you think about it but anyways).

It's been described as a roguelike starship combat simulator but I prefer calling it a procedureally-generated-death-maze where "Easy" difficulty is challenging, "Normal" takes incredible skill and tactical genius to win, and "Hard" is the stuff of nightmares.

Combat is as smooth as silk, events are varied, it's got a free DLC in Advanced Edition, and the OST by Ben Prunty is simply sublime. Check it out: it's definitely worth your time.
