Age of Empires 2- multiplayer game economy score too high. suspicious to cheating

I don't think he's cheating. The first reason is that Allow Cheats was not checked. The second is that a high economy score does not seem like sufficient grounds with which to accuse someone of cheating. Economy score = 10% of all resources (spent or unused) + 20% of resource value of surviving units and buildings except for Castles and Wonders. A high economy score is more likely to be due to legal in-game means. Reasons including:

• Your opponent gathering more resources by having more resource gathering units. Given the high components of food and trade, it is likely that he had more villagers and/or fishing boats for food and more trade carts or trade cogs to generate trade profit (or made the trade carts travel to markets separated by greater distances). This contributes ot the 10% of all resources component of the economy score equation.

• If he won the game, he likely has more surviving units and buildings. This contributes to the 20% part of the economy score equation.

This somewhat also fits in with him using many elephants. These units require a high amount of resources, food particularly, and he would have thus placed a greater emphasis on collecting food. Elephants are strong units, and he can get away with using smaller army sizes due to their strength, as opposed to non-Persian teams which cannot access elephants and must thus compensate with a larger number of weaker units. Given a limited population limit (the standard being 75), with a smaller army, he can afford to have more units dedicated to gathering resources such as villagers, fishing boats and trade carts. This would have a greater impact over a long match, which gives more time to produce elephants and for resource-gathering units to produce resources. This match was indeed long being nearly 3 hours long.
