The team at Heyzap yesterday launched payments to enable virtual goods for Flash games.  This is really neat because it is exactly the kind of thing that is difficult to do for an individual game developer or publisher but delivers value to the whole system.  By difficult I don’t mean from a technical perspective, but from a social and network perspective.  For long-tail casual games, endusers would not necessarily trust an individual game with a payment and the incentive to buy currency that can only be used in a single game is much smaller as you are much more likely to tire of a game.  Similarly, for many publishers Flash games are an addition to their core site for which they cannot invest in additional support technology.  There are many more great things on the roadmap for Heyzap for both game developers and publishers!
