Woohoo! Let's get this party started!

I do wonder about using a game to determine battles if people can't agree on an outcome though. How do you account for some races being just superior in a purely physical sense? Or technology levels or myriad other things?

I'll marry things as best I can, in the event that I am asked to resolve conflicts. 

It will not be perfect, but it will be more dramatic and fairer than a simple coin toss. 

A simple scenario though, for example, would be if my Dwarves were invaded by a fully fledged Promethean army. 

Dwarves = Citizen soldiers with no real training, and ill-suited to open ground combat where their size puts them at a disadvantage. However, numbers are on their side.

Up against a Promeathean war band, of hardened and trained warriors. 

It might translate as: 

10 Roman Early Cohorts vs 20 Greek Militia Hopilites. 

I'd test the battle first, to ensure things look kinda right (the other army doesn't rout within a few seconds)

And then I'd have at it. 

The casualties sustained on both sides would be computed into a percentage, which would then be given unto the RP. SOOOOO:

10,000 Dwarf Citizen Soldiers vs

5,000 Promethean Warriors

Dwarfs = 78% Casualties, ending rout

Promethean = 60% casualties, victors. 

I could then be like "The Dwarf Army suffered grievous casualties, forcing them into a disastrous rout; meanwhile the Prometheans themselves, though victorious, sustained losses they could ill afford to replace." Which would translate into a minor Promethean victory, but perhaps a strategical defeat.
