God of War III is the best in series. Balanced difficulty, true to it's core, great ending to Kratos' journey.
The scale on the game is amazing. The level of details, fantastic. Even with a lot of things going on in the background and Kratos facing a lot of enemies, and believe me, there's a lot of them coming to attack you at the same time, the frame-rate never goes down.
The history follows exactly where God of War II ended, with you climbing Mount Olympus, and finishes exactly what the previous game started. It's a great game, and true to it's core. People can say that there's no dept in God of War games, but it never betrayed what it meant to deliver.
This series doesn't try to be more than it really is, and that makes these games even more fun.
It's also impressive how each God of War game had a different director, and each one was able to improve the game while the series advanced.
This game is everything someone would expect for a God of War game, with more things to see and feel. The battles are epic, the bosses more fun to beat and the puzzles are good as always, not too hard, no too dumb.
A great ending to the Ghost of Sparta's epic journey, a must have for all PS3 owner.
