This is my partaking of this Halo conversation. Warning, very nerdy.
I played Halo 1, Halo 2, and the Halo 3 Beta religiously.
Halo 1 was a landmark in gaming. It introduced the regeneration of health concept, it introduced tactics of long range, as well as close range, while still staying neutral between over the top arcadey blow em up (unreal, quake) and being too tactical (rb6).
Halo 2 straight up bombed. The autoaim is retarded, I know people who seriously started playing at my house alone who can 4shot like nothing. Its crazy. Halo 2 is just a game where it takes no physical skill, its all out smarting your enemy and working as a team. In Halo 1, especially on the pro level, it wasnt completely unbelievable to hear about Walshy getting a Killtacular off Team DM, or Strangepurple getting a 6 shot double kill on the OGREs. Sure, the nifty new graphics and new style of gameplay was great, but it was too much of a change. They took out everything that made Halo 1 fun, besides the 8 on 8 gameplay, but that lost its luster fast, especially after Big Team Battle and Major Clanmatch were introduced. What made Halo 1 fun was the fact that to get GOOD games, you had to put effort into it, halo is like sex, easy sex with one girl is only good for so long, then it gets boring. Ive been on both sides of this analogy
Halo 3 beta is what Halo 2 SHOULD have been. Its brought back characteristics of Halo 1, but its still its own game. Less autoaim, minor adjustments to the game physics, and wayyy better graphics. New ideas, new controls, its going to be a great game. Halo 2 was rushed, and they learned from their mistakes, now its time for Halo 3 to close out the trilogy in style. But we must all remember to pay homage to the great Halo 1.
