Board Game Arena

What's the difference in the rules between the first edition and 2019 edition of CoB? I don't see much difference other than more boards in the 2019 version.

The biggest difference is one of the Yellow Tiles (#6) has a slightly different power.
In the original it allows you to spend 2 coins to buy a tile from anywhere.
In 2019 it allows you to spend 2 workers or 2 coins to buy a tile from anywhere.

Many people think the tile is too strong in the 2019 version (I agree), so prefer to play the original.

Two workers?? Uhhh two workers is WAY cheaper than 2 coins, wow.... that change makes no sense to me.
