AoE is a classic. Great game. It took me a little bit to get into Starcraft because of exactly the same reason! There is micromanagement but it does go alongside macro gameplay. It took me a while to really understand how to play the game. The learning curve for me was a beast. But I can say that Blizzard really has their ranking system worked out though! It didn't take many matches to get put in a reasonably competitive bracket when I started.
