...game pleasure in wood
I'm aware of one difference - the 2nd edition includes 2-player variant in the rulebook and the box says 2-4 players, while the 1st edition says 3-4 players.
2nd edition box front does not have the designer Sébastien Pauchon's name under the Yspahan title.
Also, in the 2nd edition the word "Games" in the Ystari Games logo on the box has a slightly different font; the "g" is capitalized and most of the letters are connected just like script handwriting. It's a subtle difference, but it is there.
