I’ve been working on a couple custom maps with triggers and extra stuff to recreate Empire Wars for AoE3! These maps are in my map mod (browse the mods for “vividlyplains custom map pack”) or in a standalone mod called “vivids empire wars”.
If you’re unfamiliar with AoE2’s Empire Wars, you’re essentially jump-started into age 2 with an appropriate economy, etc. On my custom maps, you’re supercharged about 5-6 minutes into the game with some prebuilt buildings, wagons and rickshaws for more, preresearched market techs, extra starting vills, a starting shipment or two, etc . . . I may post a complete list here at some point but it’s a lot so I encourage you to get some others and play on it yourselves! There is even an extra custom win condition where you can win by stockpiling x amount of resources and XP. The win condition shown in the image below is for a 1v1, the amount you need to stockpile increases proportionally to the number of players.
