Trail Scenario is a sort of B&D scenario where you have 100k of all resources and a 100+ man army in the imperial age.
The player is given a B&D start, with a normal city, many villagers, resources to be gathered. But why? You have 100k of everything. Theres nothing to do in the scenario but move out and smash the enemy city.
Its broken for two reasons. You have infinite resources, so you can easily win by spamming expensive units. Or you could launch a blitzkrieg with just your starting army, which is huge.
No real attempt was made to differentiate itself from a black forest deathmatch.
