We have a clear game issue: Some players become too enticed with the trading part that lose their interest over everything else and most importantly; war.
What extra interests can we give to these players? Let's suppose that they would not be interested enough to war as war has risk and risk is not something they would like as they mostly possess big trading fleets. We need new concepts for them.
Besides these, we all want something extra when we play the game. What this is?
You can mention existing ideas. Just keep it short and to the point. If everyone could post here, it would be the best. Don't be shy!
