You can play population cap 200 to 1000.
A lot of buiding are build (same as your enemy)
you start in post imperial age , and you must be Huns civ because there are no house build.
Villagers don´t exist.So you cannot repair , build.
To win ( especially if you play cap 1000 pop)
try to train faster and manage well your troops.
Good luck , it will be a hard fight.
