Hi to all!
I've just recently joined the forum and have enjoyed reading through it. Outerra looks fabulous.
I have tried to read a broad set of posts to get a feeling where everyone is at. I have a suggestion which has probably been thought of already so apologies if this is a repeat
How about a demo world/s on a server where the various modding community can ask for a spot of land, maybe 10km square and they can develop (as in create models, add necessary code etc ) what they like (within reason) on that plot of land.
After some amount of community development you could then travel round the different plots seeing the novel uses people have found for the engine.
I can imagine there may be a few technical problems with this, such as how to seamlessly travel between plots when you may not have the assets/code required to view the plot.
Any plots the Outerra team really liked could be moved to "demo island" or where ever and be shown to potential engine customers.
This way the ARMA devs can make the ultimate tactical-shooter, the flight simmers can create the perfect flight sim, the city builders can work on creating huge metropolises and the list goes on.
Anyway just a thought I had
