I'm really curious as to what the first commercial use of this engine will be.
im still guessing, that it will be some terrain survey or physical/naturesient. simulation thing for regional and global scales ...
for mil-sims (and other real-sims), the biggest problem will be the size of the planet to be cowered by objects. Simply, if there will be no way to fastly and enough realisticly/detailed import urban and technical objects in its vast spaces, no one will try to go seriously on it ... that just needs a opening of such vector data from various survey companies at reasonable price in global scale (means of possible import in future already discussed on forum). Or good rural-generators for OT. -- Can be seen on DCS, how their world looks like, and no "refurbishing" plans on that in minds, cause it was a pain in the ass job to hand-pickly go trough all the cities and towns. But many projects of solving such problems are in the world, so we might see something fancy in a few years, till OT hits the V-1.0 state.
Detail of simulation is a big thing too - aether some simplifications are in place and making an ARMA-like sim, or going on hardcore whyte every piece of tech-params., witch has an per-vehicle outcome. Personally, i would be really glad to have an DCS handling detail level on ARMA type of gameplay options (... but i see already all those people monkeying about start up procedures under overrunning enemy fire.
- Arcades just win this fight in numbers.
) BUT .. if a serious military issue sim would see its dual purpose in gaming applications - imagine the russian spectrum training sim going OT and in lightweight version (mil sims have the secret stuffs there, we have to understand) to the gamers market ... we just have to do some deal whyte US/UK/GER/FR/RF defense ministries for getting the info, skilled minds and funding.
Actually that may be a good way to go ...
