And
now it begins.
343 absolutely has to take control of this opportunity. The fans are ready, Halo has the chance to make a drastic come back.
EDIT: Interesting discussion here about competitive Halo. Puckett mentions CE not having online (it did) and then spoke highly of Halo 2 (rightfully so, but it's also the game he grew most with in the public scene), and then he mentions how Halo 3 was a decline in gameplay because it pretty much artificially forced teamwork on you instead of allowing a single player to be really effective. It was like this in Halo 2 as well (button glitches helped with the speed/feel of the game though, regardless of intention), albeit not as bad, but it just goes to show that Halo 3 could've arguably had a hand in the competitive decline of this franchise.
After Halo 2, the next game was going to be massively successful regardless. Halo 3 was inevitably going to become popular in the competitive scene as they entered into the HD era and brought with it features like Theater and Forge. The
gameplay though was definitely not what it should have been after 3 years of Halo 2 and fans wanting a faster, more consistent and skill-based Halo game.
If nothing else, Halo 2 Anniversary has the potential to bring Halo back into the competitive scene and Halo 5 to blow it out the water. Either way, the time feels right.
