5 stars for fun factor, -2 stars for sustainability of fun= 3 stars.
I like this game much more than other real time games of this nature because of the aesthetics and the higher level of customization of tribesmen and the island. For the first few days, waking up and checking on your tribe is like Christmas. The trophies are attainable and there are very exciting technologies and buildings for your tribe to unlock. The problem is, however, that there aren't enough things to unlock, and most of the trophies are obtained too quickly. It gets old once there's nothing left to do but keep your tribe alive... If the games were cheaper I'd recommend this game because it only provides a couple weeks of entertainment, but it was very fun while it lasted.
