Yeah that was kinda unfair,
to those with mental illness.Seriously though,if you cannot find rules to play at that scale,then you should come up with some yourself.You would want the rules to fit at what scale you want each piece to represent,the smaller the scale the simpler the rules should be to form.Fire and movement would be the easiest to figure out,then if you have vehicles involved you would want to figure out a good damage system.Any way its just an idea.
