The problem is that Licensed Games tend to be mediocre at best. But why? There are two ways to sell video games: Quality of game, and reputation of name. Most video games that sell fall into at least one of the two categories.

Of course, movies based off video games don't tend to go over well either, for much of the same reasons...and yes, this Trope carries over into other game mediums.
