Nice idea It's actually super-easy to upload WIPs (you can upload the .blend file with the light setup and just package the texture used). Here's the ptolemaic house model I'm working on the ptolemaic structures thread: http://skfb.ly/5lk4hed0a
Can you implement a break formation option to the formations menu? Scatter is not a break formation option as it is very ridgid, being basically a formation where the units keep a set distance from each other. The fact that a group of units have to be in a formation can sometimes lead to some absurd situations e.g. marching in a battle line to a construction location. The fact that animals are also bound to and move in formations can be ridiculous as you can see in this screenshot: Sorry for my formal reportish english.
What do you guys think about uploading 0 A.D. music to Soundcloud? Mobile users prefer this service, it's very popular nowadays and it allows music downloading. And Bandcamp doesn't, by the way. And you can always link Soundcloud account to Flattr so we can support 0 A.D. musicians directly.
