Have you ever been bit by the bug of absolutely needing to get something done and finished just so you can keep riding the high of finishing something? You chase that feeling into the next thing, and the next thing, and so on.

Brandon Sanderson and writing is a similar example. Is the quality always there? No. But, the guy is very very good at finishing and clearly rides to wherever his passion takes him. His output is, in comparison to other authors writing in similar genres, incredible.

Also, games were much simpler and players had much simpler expectations.
