Gauls get: Tavern and Naked Fanatic.
Britons get: Rotary Mill.
So, now all Celts get Rotary Mill, but also a unique unit-producing building.
Britons now have a better demo "sandbox" map.
Ptolemies now play like they are intended. Just need tons of new artwork. ;) Try them out on the demo map: Sandbox - The Ptolemaic Egyptians.
Some highlights: Their Nubian Archers train very fast, but have a finite life. The Lighthouse can be built on the shoreline (but looks like a library). Their Military Settlement works as intended (can be built in neutral territory, but min distance of 80 meters).
Testing out: Farm field limits (+8 per Farmstead, +2 per civ center).
