Good luck with the project
I look forward to more descriptive and visual explanation of the Project at the moment its obviously to early to judge , i see you already speculate about damage and things so will look forward to see these implemented when its possible too , i wonder if you will do the break up of ships and parts of in the atmosphere etc too.
looks like a nice conept for the engine , have fun and remember to keep it simple at first within the confines of what you are able to achieve , i see so many porting ideas fizzle out when the application of animations and decimation of models are required due to FPS etc and scripts become necessary.
