Interesting bit of RPG Makerish News I Seemed to Miss
Thought I would link to it, the idea is so nummy. Generating C# assemblies for XNA on the 360 would be a fun trick to master. The RPG Kit for XNA is pretty nifty as a starting point. Perhaps in the same way that TorqueX 2D works on top of XNA, though with more built-in functionality and less coding, of course...but with C# rather than Ruby for the code junkies out there experienced with the RPG Maker realm.
