Scott Bilas at Oberon Media has written an interesting white paper on the rationale for using Flash as a platform for casual gaming. I think it is an insteresting article, with some good references and tools mentioned. If you are into building games in Flash, this is a good document to have in hand when convincing clients and/or investors about the merits of Flash as a platform. The unique perspective, is that Scott comes from the traditional gaming industry, rather than just being yet another Flash developer who has realized the incredible power of FLash to make compelling games.
