Totally agree on blue/red. This is standard in most military games, including actual real-life war-gaming. Blue=Friendly, Red=Enemy.
Also, I do not think the resource panel should be horizontal either. It's much easier to take in vertical information when there are separate categories. There's a reason you almost never see tickboxes in software arranged horizontally. Bulleted lists are also never horizontally arranged. It would be ugly and hard to read. Note that they also used a serif rather than san-serif font for the income numbers. Sans-serif is much easier to read on computer screens.
Excellent points! Agree 100%
