While Angry Birds may be the most widely known video game app on iPhones, iPads and Android devices, it is hard to argue that there is a more addictive game than Temple Run and the obvious follow-up, Temple Run 2. It’s a game that has no end. The challenges just get tougher and tougher as you play. So, if you have it downloaded on your phone, hurry and load it and pay the $0.99 to use the Fastest Man in the World, Usain Bolt. This probably should have been offered at half the price, since he really isn’t any different from any other character. There is no benefit when upgrading your chracter when playing this game. His lightning bolt special power isn’t anything different than the normal speed burst for the characters. Barry Bones is just as fast as Bolt, as is Karma Lee. But it’s a novelty, and a fun one. Just keep playing.
