This game has some terrible balancing issues. Some GBs are outright worthless like the Colosseum, which is a shame because colosseums were a very iconic part of the Roman Empire. Compare that with Alcatraz that let's you eliminate everything but one Rouge Hideout at a high enough level while having more than enough troops. Speaking of units, they are poorly balanced as well with the worst offender being the Hover Tank. It's so bad that it makes all units in the AF obsolete before you get them and possibly OF units as well. I understand you need to make money, but how does some things being useless and others breaking the game help you make a profit?
