Here is the pitch – create a mobile flash game, or HTML5 game portal with a handful of games that will work on the small screen. (Kongregate and Mochi Media have done this already)
The difference in my story is that you borrow from the music business and cache any game that is being played so that it can be stored for offline use.
The reason this is compelling and different from an app of an individual game is that you can have a constantly updated catalog (the way Mochi, Kongregate and Addicting Games do) without being controlled by the draconian Apple Store.
The mobile web is coming and coming fast, the faster you can replicate what the big established web portals are doing but as mobile experiences the better.
Down with the app tyranny!
