That game I was thinking of was called Imperial Glory, not Empires. It had all the stuff like taking and holding fixed positions like buildings, naval combat etc.
My chief worry in this is that the pace of battles will be so fast you will be playing in increments with the pause button. I certainly hope they fix musketeers.
In Kingdoms they automatically turn and face the enemy, which leads to them ending up in random positions voulnerable to enemy mele, pretty useless compared to archers which can be placed anywhere and will shoot over the heads of screening forces and won't turn and ruin their deployment.
