Our game will not suddenly change next week, it will take Hitech a few years just like we went through getting AH3 live if he wanted to implement an AI ground war for short attention span younger players to shoot at and grind out rewards, ranks and self esteem.

However, I would try to get it out as soon as possible and tie it with Steam 'Early Access' to have new players coming in.
There are plenty of games on Steam on 'early access' where the products are not finished but people are going in to play them because they enjoy being a part of idea of an evolving game.
So even if HTC would start working on this and it would not be finished, by having many players testing it AND paying for the game at the same time, HTC would have new players and player feedback on everything, and when the game is on 'early access' people understand the game is not finished so they are more leniant and forgiving towards everything.
It would be a win-win for everyone, and by having the game on Steam 'Early Access' HTC could also judge if the idea is worth pursuing by player reactions towards it.
Sometimes only the 'idea' of something can be even a more powerfull advertising than the actual game itself because it makes people imaginations run wild, the idea is here of a 'ultimate WWII multiplayer combat game'.
There is a game called 'Rust' which is in early access now for over 5 years. Which promises a 'sandbox fps' where players can build structures, and it sells very good, because developers constantly update it by adding features which complete the game and it has 40,000 players playing it.
So HTC could be making this, while players would be playing it, this way the game doesn't burn if HTC would spent 5 years making it, and then no one would want to play.
Adding features which complete the game while players are playing it, only makes the people feel the developers are working and updating the game, which is only a plus and keeps the peoples spirit high which translates into good reviews, and good reviews make more people come in.
The Steam Early Access + WWII could be a separate thread on its own.
