If content earlier means tons of bugs, then I would prefer to wait an additional month or two instead. Also.. what you mean under "important things" they should focus on? The given game is THEIR PRODUCT, it should be the main focus, not the will-be-sold DLCs. (from which one was already available a lot earlier and in some cases a lot better made: the official house DLC) Of course I understand that they are a business, and they gain basicly nothing if they start patching up something from what they already cashed in..but still, owners of said games shouldn't need to rely on the good gesture of random modders, neither need to learn how to mod themselves just so to fix bugs found within the game.
Never played the Fallout series (more than 5 minutes that is) but the TES series have gone somewhat on a downhill in regards to quality (at least its noticeable in the storytelling as it gets more and more cliche-d after Morrowind) and most of it's popularity comes from the mod-support as it keeps the games fresh. (which is the doing of non-Bethesda-affliated modders)
In regards to the "fixes important things".. I don't know about you, but I never had noticed any problems with resistances UNTIL they broke it totally by a patch which wasn't even supposed to touch that... and I didn't even mention the backwards-flying dragons. You must be lucky btw if you haven't encountered any game-breaking bugs (I personally encountered only minor-quest problems and the usual awkward moments) as lots of people were unable to do the main storyline
because of a certain someone bugging out. Of course random modders found a fix for it.
Btw, I didn't mention anything about "having more content" as sure, the game shipped with x content, okay I deal with it, but then they shouldn't try to trick me with DLCs which content was already made by others a lot earlier.
I think it's fair to reference it if the behaviour is a reoccuring one and in this case it is. The unofficial skyrim patch fixes a lot more than the official ones. (which actually broke at least as much if not more than what was fixed)
