What a bunch of cry babies.
Microsoft bought Bungie, get over it. It's a business.
Bungie owes you nothing. They make great games, you buy them and play them. You get enjoyment and they get money to keep making great games for you to play. Pattern repeats.
If you think Gearbox will fuck it up, read the reviews first.
Who knows how Halo would have came out if Microsoft didn't buy them. Could have been the next vaporware like Duke Nukem Forever. We could still be waiting for it.
If you like to play Great Games, then play Halo.
End of story.
