In My Tribe, you are trying to save your tribe of villagers from disaster by sailing to one of millions of deserted islands in the ocean around you. The 5 adults and 2 children in your tribe will sail to any island that you desire, and you begin to try and save yourselves by fishing, gathering wood and rocks, building huts and science stations, and more. During this time, your villagers will gain skill points that can be spent on other technologies as you progress through the game.
The story line itself in My Tribe is great, even though it is extremely similar to Virtual Villagers. The main difference is that once you have conquered your starting island, you can then sail on to other islands, ensuring that this game will last a long time for the money spent. Your little villagers will even miss you and beg you not to log off when you have to go for the night. So, overall, I give the story line in My Tribe a good 5 out of 5.
