Great map. Only problem with it is that Africa can only be attacked from 3 countries. This makes it very easy to defend it becomes impossible to attack. Even in regular Risk, Africa can be attacked from 4 countries.
Another problem is that the cards are fixed on 5 and you can't change the default. It should increase in units of 1. What help is it when you get 5 armies and the borders are all defended by 35. Also, no point in taking someone out for just 5.
