but there is always another factor to consider - realistic is not always GAME-GOOD.

I have to agree with Wave Skipper. It's virtually impossible, within the mechanics of the game system/program/engine, to replicate matters on a full, 100% historical/realistic basis. There are literally thousands of variables to consider, and trying to program for all those variables, well . . . it'd be nice, of course :p

From what I've seen, most of the serious modders try their best to keep things as 'real' as possible within the mechanics of what they have to work with. The old expression "You can't make a silk purse out of a sow's ear" comes to mind. But the modders here usually do an extremely good job of coming doggone close.

Sometimes, though, you're just going to have to compromise, somewhere. The result might not be totally accurate and realistic, but as optimal as you can.
