1st time i played Halo 3, i only liked it, i thought it was a quality game but it just didn't make an impact on me. I didn't care for halo 2 either.
But then, a couple months after it launched, i played halo 3 again, but on heroic, and i fucking loved it. The way you can approach the battle is second to none on consoles at least, the sandbox nature of it rocks, and suddenly the game just starts opening its legs to you and then you thrust and you thrust until you fucking come.
I found new respect for Bungie once i finished Halo 3 for the 2nd time, i became a Halo fan. Only problem is, the story is interesting but it's not well covered in the game, you kinda have to go there yourself, the cut scenes weren't brilliant either, animation wise it could be pretty weak, and some of the visual aspects like the characters faces and shit were pretty bad, something that really shocked me since it was such a high profile game.
I don't know how Bungie gets away with that, i mean it's like the biggest game on earth or something, harcore wise at least, and it had a lot of money behind it, and in the end it just feels like they spent all the money working on the multiplayer, a portion of the game that will only be played by 10% of the userbase that will buy the game. I don't know.
Halo 1, it was good, Halo 2, heh, co op was good, Halo 3 however i don't know, it made me excited for a sequel, but if Halo 4 or Halo Peter Jackson (Does that even exist) doesn't come up with something better in the presentation side, i'll be pretty dissapointed.
