Learning from Dragon Age II, a title I loathe with more hatred than anything Harry Potter, I actually did make my first Dragonborn look very silly, with strange black eyes and a very peculiar protruding chin, expecting to make it easier to spot my own character in any nonsensical cutscene to come, should there be any. Luckily, most of the story had me experience it while in first person.
Everyone using "invisible helmets" should, in my very own, not too humble opinion, go back to play some Barbie or other make-up and dress-up game. I spent about an hour with the Dragon Age 2 face-creation kit, but the game annoyed me out of my socks after not even an hour of actual gameplay and a felt ten hours of nonsensical cut-scenes with annoying accents and a beardless dwarf.
I do hope, however, that Bethesda will find the time and motivation to put the amassed funds to good use and, well, reinvent their engine in a less buggy way. Some of the bugs I encountered were little more than "fun" and mildly annoying, others grabbed immersion by the floppy ears and spun it around just for the heck of it. Oh, I just remember another fun one: Sitting down to improve my blades, but the smithing subgame just never starting. Life would go on around me, people would come, chat me up, go to sleep, get up in the morning - I was frozen trying to sit down to sharpen my tools of destruction and make some cash off the 300 pounds/kilos/stones of surplus weapons. No can do, said the game. So I saved and called it a day. Next day, When I loaded from that very last save... yeah, I was still stuck. It already happened with the funky enchanting table, but that only lasted a couple of minutes at the very most. Not so this time. The whetting stone was cursed, and about ten minutes of trading, improving and making the inventory a little less cluttered were lost. All hail the Autosave!
During my trip though Skyrim, missing actors seemed to be caused mainly by dragons randomly eating them, or my misinterpreting people attacking me for whatever reason as valid foes worthy of beheading, but most of the time the engine did acknowledge my errors.
If, however, some quest givers call the cops, er, guards on me after I enter the instance they asked me to clear out, or the radiant engine orders me to interact with people who have been dead for weeks, I somehow come to believe that that particular bit would have needed a bit more polishing, and I would have preferred less bugs over yet another incarnation of Herbert West's face creation kit from beyond.
I think other obviously mostly missing content like the bard's college are very well missed opportunities fed to the deadline demon, but in the bigger picture - and Skyrim is close to being a rather crowded Hieronymus Bosch tryptich as interpreted by Geof Darrow - it's not that big of a deal, just yet another nice-to-have-had that could eventually be fixed by some Bard's Tale expansion.
