Deus Ex: Human Revolution - Director's Cut [Steam store page]
While the story is weaker than the original, this FPS-RPG still offers many viable playstyles - and a visually stunning world. And the Director's Cut does a slightly better job of integrating the DLC, although they're still sort of an independent experience.

You also get a few other perks like developer commentaries, although these don't have any visual indicators to show where they are, so they're hard to locate and activate as you're playing. The redesigned boss fights are a nice touch though, and definitely a welcome change compared to the originals.
