IDK if there has been a topic about this, probably has, but I am in a hurry and don't have time to search.

So if there has been an update on the 360 plez say so, and if yes, would the update be on the dixc if I bought the game today?

There has as far as I'm aware been one update for it on the 360 so far, with a larger patch currently being worked on.

The updates won't be included on the disc until a new version (probably a GOTY edition) is released. Until then they will have to be downloaded.

does it fix the game breaking bugs. (some think that there aren't any, but I have seen otherwise.)

Im talking about 360 version, they usually place the latest patches when they make more of the discs. they did for oblivion.

With regards to the game breaking bugs, that depends on what you consider to be a game breaking bug, as some people will shrug off something that someone else will find unbearable.

Personally while I've encountered some bugs, I don't consider any of the ones I've encountered to be completely game breaking.

Having said that, I believe it's the currently being worked on patch which is the one which should be addressing most of the major bugs.
