The pace of the game. I know a lot of people are saying it's too slow, but I like it. It gives me a chance to really enjoy each new development. I look forward to the announcement each day on what has been added to the island.
I love the pacing. The fact that things develop slowly and over time, and not necessarily all overnight is wonderful. It always makes me excited for the next day--seeing what will happen, if there are visitors, any new buildings, improvements, etc., and I'm glad they kept the daily announcements when moving to NH as well!
