Skyrim is getting huge sales numbers and perfect reviews everywhere you look, with shortages in some places, but suffers the same problem that all Elder Scrolls games have: It’s buggy as hell. Bugs, glitches, and exploits are no stranger to the series, but a rather crippling bug on the PS3 version has resulted in the game winding up unplayable when the filesize reaches a mere 5-6 megabytes.
Pete Hines, community manager of Bethesda games has said he doesn’t know if the latest patch will fix all the reported bugs, saying “We will fix as much as we can for your platform. I don’t know if it will fix -your- bug. Takes a while to test/fix/regress. Hang in there.”, he is also unsure of when the patch will be released. The creation kit to allow custom content and the bug fixes are both being worked on at the same time.
Even though it has been in development for a while, the testing a game gets from even the most skilled examiners in the industry is nothing compared to the sheer manpower of millions of gamers. Missing graphics and save files getting too large being the most common complaints.
I think the savefile problem is the biggest issue right now, as the game keeping track of that many details at once renders the massive world unplayable after a while.
