The absolute worst, in no particular order...
-Region Locking
-Online Passes
-Paid DLC (for any game you paid for IN FULL at upwards of $60 (or more for collector's editions))
-$60 retail price tier for all new games, regardless of their budget, size, length, features, etc.
-DRM of any kind
-Being forced to pay to play X360 games online
-Console subscription plans (example: X360 at $99 w/ overpriced 2yr contract)
-Paying more to download a game than buy it at a retail outlet
-The lack of overall promotion of Indie games on any given platform (IMH the most creative games this gen)
-No new companies attempting to enter the console race
EDIT
-The utter lack of Free-To-Play gaming on consoles
EDIT
-3D gaming
