Well, ideally, you will get 100s of hours of playtime, that's our eventual goal (not sure if we're there yet, but there's still a TON of content). But, with the way the game is designed, you should never have to "restart". Sure, you can if you want, but every time we add something, we do it in a way that you can find/use it in your current world. So, replayability in the traditional sense isn't necessarily the goal, but as long as the game is selling and there is community support/demand for it, we plan to keep adding content/things to do.
