There are many reasons to buy a short/single player game at launch, you may be surprised but people can have more fun in those 10 hours of killing monsters using their great reflexes than grinding 50+ hours through a RPG, or trying to get a kill streak on a multiplayer game. And if they don't support the kind of games they love and have fun with, companies will just not do them anymore.
Yes, not all people can afford to buy short games because they have to take advantage of their small entertainment budget, but the people who can do it, will do it gladly if that means having fun and getting more at a later date.
