@OverRated_AU - wow. That IS quite a list 
As soon as I’m running out of things to do, I’ll take another close look at it 
Although my first quick glance tells me that I’ve already got most of it on my plate (except for specifics like naval units, maybe).
In the meantime, I’ve added a pretty modular minimap, with terrain layer, custom unit drawing (e.g. for hero units), view frustum, scrolling and minimap orders:
Also, I’ve added player teams, pretty much based on the good ol’ Unreal Tournament way of doing it. Now, I’m deep into building construction. I wanna make sure that it works like you expect it, and is still customizable enough to be useful for you (e.g. constructing buildings works fundamentally different in C&C than it does in WC3). Stay tuned!
