So I've been following this project for a long time and I've not seen much movement in any direction. So I have a suggestion that may get us started and get some momentum to get started.
Looking back at the very beginning commits when the project first went up I can see that imho the project looks a lot better organised - the later stuff is suffering a fair bit of confusion.
My suggestion then is to focus on only one bit to get us all started; I propose looking at the render project to get it converted to XNA rather than DirectX?
This will require upgrading the framework version but without changing too much straight away. The idea being if we get the system up and running again we may attract a few more people to start migrating to MCV / WPF etc...
Let me know your thoughts!
