Let's look at this scenario in detail. The idea is to examine it from all angles and find out what is the best outcome.
You were originally in Africa, but you decided that it was too competitive and if you stay there you will be squeezed between Brown and Yellow. So you decided to leave and make your luck elsewhere.
You went to Asia and adopted a strategy of slow concentrated growth. All you wanted was not to get kicked out of the game.
Meanwhile, everyone else was busy conquering their continents secure. Blue has just managed to get his continent. Green will get Europe in one turn. Yellow and Brown already have their continents, but are aggressively competing over Africa.
Brown was clever earlier on. He made a treaty with Blue over Central America not to be attacked. He has since counted on this and has moved all his armies to a single front, which is helping him greatly to fight in Africa.
All players are quite experienced.
