I really enjoy the first 15-20 turns of every game. The mad dash for planets, anomalies, and resources. Then around turn 30-40, you can usually count on a defensive battle or two. After than, it's pretty much a matter of clicking the turn button until your economic machine cranks out enough credits to buy off everyone, or your research machine cranks out enough tech to win.
I'd really like to see something to make the middle-end and end game more exciting. Maybe the appeance of super anomalies that you can only get if you own the space. Honestly, who even bothers to equip ships with survey modules? All the anomalies are gone by the time you can space the production capacity to equip ships with them.
anyway.... it's still a great game.
