I'm not going into specifics, because I want to play this game. But what if you play around with map mechanics in some way, and with Fog of War? Not like literally playing Advance Wars matches with each other, but something in the spirit of that that injects a bit of physicality into the game.
Yeah it's not literally playing Advance Wars but it would feature the fund system where you get a certain amount of funds each day and spend them on buying units (let's say for example you get 7000 funds each Night phase to spend on units). And with those units, you would use to vote against a certain other user.
So if you had an Anti-Air unit and used it against a Battle Copter unit, said vote would be worth more than one. If you had a Medium Tank and used it against a regular Tank, the vote would also be worth more than one. Even more so if the CO in question had Day-to-day abilities that give then extra firepower for certain units (i.e. Max, the direct unit specialist).
So yeah it's helluva confusing for players not familar with the series and also kinda convoluted somewhat if players don't know their opponents units. Although I guess it creates more mystery in the game.
