Flash Games
we've built a fair amount of Flash games, using a different approaches, like simple 2D, bird eye view and full 3D.
We've developed our own game engines, and used some existing ones like Box2D, most of them built on top of PureMVC.
In regards with 3D world in Flash, we develop on three different libraries, Sandy3D, PaperVision, and Away3D, we've recently started concentrating only on Away 3D for two reasons, for the fact that it's being developed by a really active community, and the fact that they are integrating their library into Molehill(the exiting new 3D API for the Flash Player).
