I recommend to finish current games with 2.6 and then start new games with 2.7.
Also, yes, all players should have the latest version installed.
2.7 is still in pre-status however.
Indeed, it is the good one!
My problem when searching for it was that the map was not looking the same as the boardgame; but you are right, when looking at it closer, I could see that the connections are the same…
Thanks a lot!
