The game is composed of an F# library and a top-level C# application. The game, a 3d clone of Asteroids, is still very far from being complete. For instance controls require a keyboard, and the code is still riddled with bugs. Never the less, the first attempt to deploy on the XBox was successful, which is quite encouraging. See Grammerjack's old blog for details on each step of the deployment process.
The F# code is written in a pure functional way, which I fear is not going to work out in the end. Such code relies heavily on the garbage collector, and the current version of the XBox360 .NET environment is known to be weak on this point.
I wonder if it's possible to modify the .NET code emitted by the F# compiler to replace instantiations of new objects by references to items in pre-allocated arrays. This would make it possible to keep purity in the F# source code while maintaining decent performance.
Right now, I feel that if I was to write code relying heavily on in-place modifications, I would rather do that in C# than in F#.
