Gear: what happens when game and RL differ?

[cosmicfish]

If it is an issue of an incorrect number (like the masses and magnifications you noted) I go with the real number. As to the difference between the reality and the game abstraction (like the FOV and aircraft detection) I usually let those go simply because that is not what I want my games to be about.

And ArmySGT. is dead right, getting the real numbers can be all but impossible, can't blame authors for going with a best guess sometimes.
