Absolutely one of the best open-world games I've ever played. The island of Panau is much prettier (and more varied) than San Esperito of the 1st game. The explosions are pretty, there's a large variety of vehicles (including jets!) to commandeer, and parachuting and grappling around the island is fun. You can get it pretty cheap now, and if you haven't already get the 1st one as well as it's even cheaper!
