MetaAOE

AoE IV and AoE II counters

Your opponent makes a unit, you read its line: the safest answer is in green, the others follow. The same counters MetaAOE shows in game, against your opponent's civ.

Unit-class rules (the game's rock-paper-scissors), not patch numbers: upgrades and army size still decide the fight.
