Imperialism 2 emphasizes decision making and minimalizes micromanagement. Never played this game back in the day but is one of the best 4X game I have played. The only downsides are the small field of view (the UI takes a fair amount of space) and the questionable combat behaviour of the enemy at times. A delicate balance between combat, trading, empire growth, exploration, exploitation and strategy. With decision making I meant that you will have to analyse your situation every couple of turns and possibly adjust your strategy every now and then (more so than in any other 4X game).
