Apparently, there is nothing more efficient at disorganising an effectual production process than a demo. However, a demo is the trademark of the product, even if it is for all but a small "your eyes only" group of people. It does not really matter how great the introduction to its display was, how much explanation there will be afterwards, or why something is not working as it should be. The bottom line is that the demo will be judged more visually than anything else. Hence it has to look as good and perform as good as the finished game.

The problem, however, is such that apart from the last production phase which is the beta the game rarely has the appearance of the finished product. After all, each and every department in the company fanatically keeps its parts of the game broken down into teeny tiny microscopic pieces on which they can constantly work on. It goes without saying that because of this it is near impossible to suddenly assemble all these little parts into a working game, which will at least resemble its ultimate version. Even if elements of the game have been considered finished, it is often the case that they need to be at least partially redone, in order to function properly with the other pieces of the constantly changing game world.
