spain, china, sioux, brits all have good early game and good fortress age.
Ports have an OK turtle and a great late game, one of the best.
Iro, otto, aztec and China all have very good team cards and are not considered broken or OP on their own.
Russia, Japan, India, France, and Germany are widely considered OP because they have broken rushes or laming strats, and/or their lamable units beat their counters cost-effectively: cuirs, ashis, etc.
