Game board:

The desired game board is 11 wide x 12 long with tapered back two rows at 9 and 7 wide. 5 rows on each side are customizable for unit placement by the relevant two players and the middle two rows are no mans land.

It's important to have lines between tiles so players can easily see the tiles to calculate values.

Scrolling the camera is useful for seeing larger maps and larger means better graphics as the units aren't so small.

EDIT: 12 x 11 looks better, basically rotate so Left v. Right instead of Up v. Down.
