2) default gamę would be full features both to use as a mod template and play IT. Also IT would be only one supported directly by me. So its not limited demo to just allow some play. IT would be too used ti advertised projekt itself.
I dont mind thanks stuff

3)i am preparing github priject account with API description and samoles.
4) anything related to people own mod i dont mind to accept requests on periodic Basis. Its seperate folder So IT will not ruin core.
Anything related to API. Well if IT will not ruin anything i am open to any pull requests. I have no rules that "this is not projekt design So i will not merge IT".
So if you whant to mąkę mod like mikromachines + weapons then few features will be required.
My only concern is that people would start to create forks to have its own engine version and this will ruin initial concept of one open core and n mods under one github projekt.
