Gotta admit this.
The introduction of Complex Engine Management mode in Forgotten Battles was really a great experience for me.
Managing the engine in different conditions and situations, is a real thrilling experience.
Things like not being able to do a power dive going 500mph blindly, having to watch out for over-revving the engine.. not being able to just switch on MW50 whenever and whatever way you want... watching your control over the throttle.. having to watch coolant and engine temperatures... setting radiator positions, controlling mixture and etc etc..
...
I'd like to sea more complex engine management options in AH2, too. But I think half the fun is learning which guages mean which, what to watch, which situation to remember and etc etc.. I don't think adding in a separate 'crutch' guage, is a good idea.
