I fully agree with this. Maybe the Aztecs could get Chinampas as an unique economical building which can replace the [Farm] for them.
Yeah, that would be nice. Maybe some of the cheat units that were suggested by other users (including you @SirBarnzy1) from this thread that I created last year could be used as a reference for potential cheat units in the future.
Leppich’s Airship for example could be a new cheat unit. The airship was designed to have compartments for dropping fuse bombs and had gun mounts as well around its perimeter.
