The expansion apear to geared to adding additional players. Is there a problem If I want to replace one of the original 3 races with one of the expansion races?
If this is possible are there any adjustments required, such as removal of any of the original exploration cards, or do you just add the expansion cards etc to the core game?
They don't appear to be geared toward adding players at all that I have seen. They CAN be used to add additional players, but it's always seemed that they've viewed 4+ players as possible, but not optimal.
