The new 2.0 update adds even more new content to what was already a decent game. I'd argue that this now boarderlines on a fairly lengthy game. I don't know if a 3.0 update is planned for in the future; but if one does drop, I could see this easily going into five star territory if it's done right.
You will easily see all the content this game has to offer within three to four hours; and that's not a good thing.
Great start, still being developed, to something that will be fun to play.
