I'm giving this a 4, just because of the importance of gold, and because of the UI. If you want this game to have a better rating, do what the people in the top comments say, and this might just turn out well.
One of the most realistic zombie simulators I've seen. It's got just about everything: random events, multiple ways of winning the game, nicely drawn graphics...The best game to hit Kong in a long while. 5/5
