I haven't been on here for quite a while. But regards use for the engine or a game from it. I think as a sandbox world it would suit a vast war-gaming world, modern or historic (modern for me though).
I know Titanim is touted, well more than touted and I look forward to seeing what that has to offer, if available to the public.
But yes, a vast war-gaming world, would be nice.
With an appropriate AI system.
