>I'm wondering how the game will pan out once you have people who know how to exploit it, which will change the landscape for newcomers.

I think this actually hits the issue, though in a different way than you meant. I'm not sure that there are ways to "exploit" it. To start with, there isn't a whole lot of depth and very little complexity. Additionally, there aren't really any hard goals or any flexible, open ended activities to do (like building stuff). It's also not multiplayer, so other people's activities don't really directly impact your own.
