I'd argue that games are the best use case for the Mac App Store, Steam as others have pointed out has the cost of the Steam application. For casual gamers, the Mac App Store is more than vibrant and has the same update management that Steam has, and its decoupled from a parent application. Games rarely have upgrade pricing, almost never need extensive permissions, and while quick updates can be necessary, the necessity of upgrades aren't as crucial as a productivity/professional application where one's livelihood may be tied to the updates.
