Let's compile a list!
-Digital distribution that takes away all property rights (mostly the right to resell, transfer)
-Always Online DRM
-DLC, especially nickel and dime DLC for stuff removed from the main game (or purpously left out) in order to milk us
-Region-Locked HANDHELD (3DS) to maximize profits by selling games for higher prices in certain regions; no imports of unlocalized games; no buying games when taking your 3DS on vacation to different regions
Please feel free to contribute more; we can hold a vote later.
"Well certainly with the Xbox 360, we had some challenges at the launch. Once we identified that we took control of it. We wanted to do it right by our customers. Our customers are very important to us." -Larry "Major Nelson" Hryb (10/2013). Note: RRoD was fixed with the Jasper-revision 3 years after the launch of 360
"People don't pay attention to a lot of the details."-Yusuf Mehdi explaining why Xbone DRM scheme would succeed
"Fortunately we have a product for people who aren't able to get some form of connectivity; it's called Xbox 360,”-Don Mattrick
"The region locking of the 3DS wasn't done for profits on games"-MDMAlliance
