Online Multiplayer Games

I currently have an advanced chatsystem being build with member functionalities. I would like to add game features aswell. I envision the following a games section just like yahoo games and or Zone from MSN. This would mean that the member function would be integrated with this gaming framework this because only members would be possible to play. Who ? 1. Have already experience with this 2. already have online multiplayer games ready 3. can deliver such a platform 4. Can tell me what the requirements are I prefer all these answers in a document so it can be studied. This case needs to be brought in practice on a later phase also. Waiting for your feedback. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Windows ,Internet Explorer
