We have spent several months planning, testing and developing a new game. We have been trialing a host of Platforms (Java Applet, Desktop Via XNA, Flash etc) and Silverlight was pretty much our prefered choice.
However, the more we get into the game the more problems we face, mainly down to the communication with a server. HTTP Polling is slow and in-efficent yet the socket functionality that is now available in SL4 is only really useful for a Intranet enviroment - Unless we are missing something.
Anyone have any opinions or experiance with this and the future of SL for Online Browser based games.
