I don't think it would matter.
Would it? 
Depends on the game engine and whether or not atmospheric variations are modelled.
In a vacuum, all objects accelerate at the same rate, dictated by gravity.
On planet Earth, this is not the case because of atmospheric variations; temperature, air density, humidity, etc, etc. In Aces High, which is a "virtual Earth," I dunno whether or not these things are modelled because Im not a coader.
Good question.
