My only problem here is that while I like the Europe map, making it so that we can't have colonies or even contact with not-Asia would mean HUGE changes to what went on during this time period.
Seriously, for starters [@ClocktowerEchos] can't play as his beloved not-Japan faction.
Relations with nations outside Europe were also always important.
Axing them would be a serious blow to complex politics we know Europe for.
Really, this is a narrative based RPG so I can't see why it's necessary to fear "powergaming" which is the only reason I think colonies are banned.

Of course this game is still playable and all but I would be happy if the GMs at least put my above thoughts into consideration.
