I just thought I'd post to let you know about a multiplayer game I built using PureMVC. It's called Multiplayer Memory Mayhem and is a real-time, non-turn-based version of the memory card game. Have a play here:http://nonoba.com/lucklaboratories/multiplayer-memory-mayhem
Pure MVC helped to keep everything clean and organised just as much in a simple game like this as it does in more complex applications I've built using it... So thanks to Cliff and the the authors of the other opensource projects I also used (papervision, gtween and the nonoba multiplayer api).
There is a little more of a writeup on the game on my blog:http://www.kelvinluck.com/2008/10/new-multiplayer-papervision-game/
Let me know what you think,
