I think Nova should use a different method of protection than the online log in.
Pay for play on the internet if necessary but If you bought the game for single player use only,
it could become difficult to access the game in some circumstances.
Having free servers is excellent but I feel sorry for Nova having gone through what they have.
Mapping is an excellent concept that is one of the themes in the C4 DF series.
Hope they come up with some mastery in the near future.
