I remember the months leading up to the release of Halo 2 still clearly. The date of release was firmly entrenched in my mind. After playing the Halo 1 campaign for three years all I could think about was that date. To be frank I was sadly disappointed. Thankfully for the third installment I had low expectations and now I am very glad of that.
Put Lancaster Online on the list of sites that thought campaign was too short and that multiplayer is the real reason to buy Halo 3-- not to mention the reason to buy an Xbox 360 if you don't already own one.
About.com's only real complaint about Halo 3 is that 12-year-olds play it. They gave it five out of five stars in their Halo 3 review.
Calling it the best Halo game yet, Australia's Herald Sun gave Halo 3 a rating of 4.5 out of 5 points.
Geek.com finishes off their review of Halo 3; it's got separate sections on campaign, forge, and multiplayer.
Halo 3's strength is in its multiplayer, they say:
If you're looking for an outstanding, unstoppable multi-player FPS, then Halo 3 is the game for you. Gears of War has a large and dedicated multi-player fan base and it looks fabulous, but the controls are not intuitive and so it's not pick-up-and-play easy like Halo is. Sure, the bumper and X buttons might throw people off for a little while, but Halo set the standard for where FPS gameplay was going, and H3 continues that legacy.
They rate it just short of a "Geek pick" because they ascribe much of the interest in the game as nostalgia for the original Halo.
