Query: Great game

Halo 3 manages to stay original despite being the third of a trilogy. The first Halo game on the Xbox 360, it has incredible graphics and sound, exceeding expectations.Given that the multiplayer is the most important feature to many users, I can assure you that it has seen improvements as well; the Forge (build a map) and Theater (replay matches) modes are incredible additions to the series. A must-own for 360 owners.The special features included in the Legendary Edition are fun, although it's up to you as to whether they're worth the extra money
