As a quick summary of the above, any game delivery system that makes me feel as if I pirated/hacked the game, but still lets me pay legitimately is aces in my book.
By that I mean you install the game, maybe enter a code ONCE and then it runs with no DVD, no extra client, no log in, nothing. You just click twice on the program and it opens and runs the way a DVD game with a noDVD crack works. That I have to spend hours looking around the internet for cracks to games I actually DO own like Neverwinter Nights 2 or whatever is annoying beyond belief just as having to use a peripheral system like Steam or Games For Windows Live is. If buying games legit doesn't even have convenience over piracy (like say, the itunes store and its 20 second high quality DRM downloads of almost any song for 99 cents) then what the hell does it have to offer?
