I love both games, for different reasons. While both are strategy games they are not direct competitors. EU3 has an incredibly rich diplomatic and strategic component, while battles are really simple. RTW has a great battle engine, while the campaign strategy has a lot less impact as you can trounce the enemy on the battlefield with inferior forces, and diplomacy, well, isn't. I like their focus on their own strengths, and they attract different gamers. And some like me who like both, sometimes I want cool battles in the ancient world and sometimes I want to see just how impossible it is for an introverted Indian tribe to maintain their freedom facing the conquistadors.
