Tarm: *Cough* Skyrim *Cough*
Luisfius: Which only tend to break modifications, and if major unplayable things are found, they are also eventually patched. It is considerably more convenient than manual patching, then again, if one preferred a previous iteration, one is shit out of luck.
See: Dredmor. Game still crashes on me every time I finish a "kill this monster squad" quest. Of course, it is optional but 3 iterations ago, that did not happen! Also, preferred the old crafting system since it allowed one to use the craft tools as extra containers, but eh, whatever.
I used Skyrim as a example of when autopatching can create a lot of rage. Several of the patches made many stop playing until a new patch came out that fixed the previous patch.
So many want to chose if they want a patch or not. Ergo autopatch isn't that great all the time.
