As for Gameplay and 'historical accuracy' that can only be achieved by mission design and engagement rules, assuming FMs are near enough correct, but this will always be prevented in CoD due to the limitation in numbers the game can support. This is why CoD can never represent the scale of the BoB, the best that can be achieved is a representation of a few of the raids. Mission engagement rules are hard to put in place in a general use on-line server because, for example, most Red pilots are reluctant to fly tight Vic formations, are probably incapable of doing it anyway, and fly combat spread instead for obvious reasons. The kind of scenarios flown in the MMPOG 'Aces High' were the closest I ever came with several hundred participants pre-registered and allocated to Squadrons/Units with clear rules of engagement and a moderator to kick/ban anyone who broke those rules. Oh yes, and you only had one life so you were MUCH more careful about what you did and how/whether you engaged. These take a lot of work to set up, even for a small scale representation of a few raids in CoD. I'm sure the community would really enjoy them but many would not because many just want to dogfight and get kills.
