The Elder Scrolls V: Skyrim

[Hans v Hube]

I do remember reading somewhere that like Morrowind if you left doors open in the game world the program has to continually remember this & as the game progressed the loading became longer & longer to the point of the fake error message to say the disk is dirty take it out & clean it.

With Skyrim i think there is no re-spawning of enemies so once you kill say a bear it stays there (do correct me if i am wrong) so would this also have to be remembered by the game (or if it disappears the same if that's it) ?

I would think re-spawning is a quick way of clearing necessarily data backing up/needing to be stored by the game?
Also the shops do not for long keep the stock you sold but have a bit better stock as you level up.

Would anyone agree?
