I've been playing Skyrim on xBox 360 since 2 days before release.
Bethesda seems to have forgotten what "quality control" means. Many quests are screwed up in some way (Red Eagle quest keeps partially coming back whenever you get the book, crimson nirnroot quest doesn't count them properly as I have 38 but the game says I only have 12, etc, etc, etc), the graphics are wonky in a lot of places (talking to people that are nothing more than 2 short sticks, or dead dragons that are pitch black of the abyss). On top of this, quest items, many that weight massive amounts, aren't being removed from your inventory and can't be removed because they are quest items. I have about 80lbs (or 80 kilos, however you want to view it), and growing, of quest items taking up space that could be used for carrying loot.
We (360 users) just got our first patch (3mb) and all it did was fix 2 problems that I didn't even know existed. When I say "I didn't even know existed", I'm including all the people on the internet that have been talking about the game too.
