We'll re-balance Unlock all countries mode in one of the nearest updates. It would be possible to actually complete it.
The problem is, initially we made this mode to be highly competitive with continiously harder gameplay. The primary result is the number of unlocked countries.
However, this was met not as good as we planned, so now it's time to arrange this part of the game in accordance with your wishes. There still would be sense in leaderboard: those who build their transport network in the most effective way will get to the top rows.
But, if you like the idea of current version of this mode, you would be able to make one yourself using Challenge editor and publish it for others to complete. Challenge editor is now being actively developed. We plan to release its beta version by the end of 2021.
