Oleg's original plan was to build a complex game engine, for more than one use, not just air to air battles, but also designed to eventually have combined forces, and movie making features to be fleshed out slowly as the air series developed, then full throttle when all the air theaters were completed.

Aircraft were first implemented in wars to be a factor in the ground war, so it makes sense to build a game engine that could eventually add more complex ground war features. They tried to make "every" aspect of the game engine more complex, they obviously didn't think it would take this long, if they did, they would have just built the Battle of Britain on the old game engine. Personally I'm glad they made the decision to build a new game engine, and give kudos to the IC publishers for financing the develpment as long as they have.
