Uh...ok

Reach doesn't feel like Halo 1. Halo 1 doesn't feel like Reach. They're two different games. From two different periods of gaming history.

And I say Halo 1, because everyone always ultimately ends up comparing every other Halo game to it. Learn to let things go people. If you really want to give in to your nostalgia, go back to playing Halo 1. Halo 3 is still pretty active, just as Halo 2 continued to stay active until last spring.

People are complaining like it's going to cause a magical patch to spawn over XBL which will make Reach the game that they think it should be. Microsoft will only make games which will sell. Bungie will only make games which they want to play. End of story.

tl;dr: Go play a different game if you don't like something about Reach. Still want to play Reach? Deal with it. A game, is a game, is a game. Play it or leave it.
