Time (or the 11-11-11 deadline) was not the main problem. What was missing in the Skyrim was a competent team of beta-testers (20-25), beyond the wonderful 100 people working in BGS.
EDIT: Hopefully, with the money they earned with Skyrim, they will correct this situation with the next TES or FO.
Pretty much my sentiments as well. IMO Bethesda wanted to make as big and expansive game as they could within a set production time parameter, but still ended up "rushing" a few things, possibly even removing, or at least minimizing content that they didn't have time to fully flesh out. Also it seems likely the shortened questlines are the result of a late determination that a major reliance on the auto quest generation feature wasn't working , as it made for pretty boring game play. Best evidence of this can be seen in doing all the generated quests Vex and Delvin give you for the thieves guild. Wash , rinse , repeat......
Skyrim is still, depite its shortfalls, an excellent gaming experience, but there's no denying there's a certain hollowness / lack of character depth etc. to it. A game this size really requires a producer and director, just like cinema, to mold it into a cohesive entertainment experience. I was surprised to find the game to be pretty disjointed at times. We do BIG things, but the "Why?" is lacking much of the time, and often very little changes afterwards. One example. I recently completed the civil war questlines as an victorious Imperial Legionaire , and I'm constantly finding references to Ulfric , as if he is still in power and as big a threat as ever. There's no substantial acknowledgement of whats transpired, by most (tho' not all) of the populance in each hold. It's as if there's no consideration being made to the plotholes events like this might create. In Cyrodil, your accomplishments are acknowledged by the general populance. You're the "Hero of Kvatch", "Champion of Cyrodil", or "Devine Crusader". Nothing like this occurs in Skyrim, other than some jibes by the guards, and a escalation of your promotional path to be a Thane of each hold. You'd think as a Thane that comments such as "MY Favorite Drinking buddy - Lets go get some Mead" from the town lowlifes just might go away, but nope, they've nothing else to say!
The biggest flaw with the game release though, was that not enough time was allowed for coding/ conversion of the finished product to the PS3 platform. Hopefully BGS will not put themselves in the unenviable postion of releasing a gimped platform vs. delaying a release date for all platforms again. As a PS3 player, it feels terribly unfair. And before someone sez "but that was patched!", let me say it again. The base coding is terribly flawed, the patches, even 1.4, only delay the onset of severe Frame lag and control function failure, which was the initial problem they DO NOT eliminate/fix it.
