Hardcore wargames are not for everyone. Are we talking about games or simulators?
How deep into the tactical aspect and strategic aspects are we allowed to go?
The amount of data and information displayed to the player is humongous and it is often very hard to distinguish these titles from deep simulations and professional products. Making these games as approachable and intuitive as possible is the true challenge that some developers face every day.
