I haven't seen anything posted on all of them yet here on BGG. However, Rahdo Runs Through video does show a couple of them. Didn't check out the unboxing video posted as it wasn't in English, but that might show the different sides.
There's not that much which can be changed:
The points you get for retiring workers in Age 1 & 2
The upkeep of active and retired workers
The points spread of the Morale track.
It's all quite subtle but if you want to be successful you will have to change your thinking from game to game. You also need to be aware of what your competitors have as this can alter the value you put on tiles.
A really nice touch.
