Deus Ex Unreal Revolution is a mod for the original Deus Ex that acts as a parody of Deus Ex: Human Revolution while providing commentary on the video game industry and modern gameplay mechanics. Features yellow highlighting, cinematic takedowns, iron sights, and regenerating health.
Somewhat over-exaggerated (but that's the way it has to be) and a fun parody of Human Revolution. It's fairly short but worth checking out.
On the DLC thing, I like expansion packs and all that, but now things are definitely getting out of control. I own the tactical weapons and explosive mission packs, but I agree that Human Revolution's DLC things are just messy.
