Let's say that each ATA game has it's own army. Now, let's think, what would their uniforms look like? What kind of weaponry would they use? What heavy vehicles would they use? What LIGHT vehicles would they use? Yes, the thread is overall boring and a more or less stupid topic, but this is what Kittehs do
Pimd Would be varsity jackets and people dressed like college kids. Kaw would be knights. FC would be terminators or star wars storm troopers. Gaw would be gangsters. Pimd would drive SUVs and ford fiestas. Kaw would be chariots and horses. FC floating speed bikes and space shuttles. Gaw would be muscle cars and SUVs.
It's quite self explanatory... Look at the names and graphics of each game... You'll find the answer there
