But Mac software doesn't have to use the Apple store. MMOs like WoW and probably TESO sell their stuff separately. The reason most games do go through the app store is they already follow all the rules and the store has a huge customer base. But what I said above is true. If devs don't use the App store, Apple gets no say and no cut.
