I loved Deus Ex: Human Revolution. I mean, boss battles and that rubbish ending aside, it was a damn fine game that really delivered in terms of giving players options. We're big on that sort of thing here.
The Director's Cut reworks the offending parts of the original game to make for a somewhat smoother experience, integrating the Missing Link DLC, freeing up certain augmentations, and adding in 8 hours of developer commentary and a 45-minute documentary. Thanks mugglesquop!
