This is ... well, I wanted to say hilarious, but since I was planning to buy it, I'd say sad indeed.
First, I have a number of old games (like one mentioned Deus Ex) that I like to just dig up and play with. Hell, I can't count the times I installed, played, then uninstalled Albion, Fallout 1-2, Max Payne 1-2, Starcraft, Broken Sword 1-2, Dungeon Keeper, Imperium Galactica 1-2... just to name a few in my sight. I have them all in original, and thankfully not limited to only 5 PCs and 5 reinstalls. Mind you, I changed mine more than that from the time I first opened any of these.
Second, a single player game with a rootkit and mandatory internet activation. Again, when the crack comes out -because as with all before it, it is not the question of if, but when - the very same thing happens: those who bought are suckered, those who download and crack it laugh.
So... before this misery, this copy protection started, I knew I paid because the studio earned it, by making a great game and not kicking me in the pants. Now? There are some companies that caught up with this, and patched their game to be non-CP (eg: X3) or didn't even use it to begin with (Oblivion).
All in all, we are _NOT_ delivered from DRM hell, just tossed a tiny bit further from the center of it.
