I haven't played Skyrim on PS3 and I'm not saying it isn't a broken game (the save issue described does sound very damning), but I do have to ask: What are other games as expansive and deep as Skyrim but have cleaner code?
I'm talking about games that allow you to do as much as you can do in Bethesda games. Regular console open-world games like GTA or Assassin's Creed aren't quite there. I think Far Cry 2 and 3 are about the closest things I can think of.
The point is, games like Skyrim and the recent Fallout games are extremely complex compared to the rest of what's on the market. I won't forgive the PS3 save issue, but like with most computer software, many bugs just can't be discovered until millions of people have used that software. That's what betas are for. Retail release single player games just don't have the luxury of open alphas and betas.
Maybe I'm just saying this because in the last few years I've gotten used to Eastern European PC games, which are often at least as buggy as Bethesda games. We love them for how far they reach creatively, but recognize the price of that creativity in terms of code. Just look at ArmA II -- a game that attempts things Call of Duty can't even fucking dream of, and is also broken half the time.
I'll also bring back the argument that what we're seeing is PC code standards transitioning to the console market. Obsidian (or as some of them were previously known, Black Isle) was known for its great gameplay but buggy-as-hell code in the PC space long before people got pissed at them for Fallout: New Vegas, and their games are still considered some of the greatest. From developers like these, I don't think you'll ever see code as clean as what you might have been playing on the PS2.
