I think this' what they are planning, a new sim.

Yeah the more the merrier - most WW1 nuts are starved of a good sim.
Maybe even they will get a basic engine that would allow modification to add in WW1 FM theories etc.

If they made models in Max first then they can reuse them obviously need some parts /animations redoing etc but the hard slog is done. All the historical research is of course reusable etc, skins, probably quite a lot of other bits. Still need a lot of work but lets hope KoTS coms out too, and OFF4 or whatever great !
