It's not unfinished. The Campaign is complete, there's multiplayer, and much more. It simply has bugs. Do you think 343i thought MCC was going to have this many problems? Also, people who are "pro" at a game doesn't mean they know more about it. There's books about Halo that people, myself included, that read and can learn from them. A "pro" player just means that they're better than someone else. And wether sprint belongs in Halo or not is an OPINION. No matter how many people say that it doesn't, it's an opinion because it's not a solid idea like, "The sky is blue". I am not really bothered by sprint, after all, Spartans are supposed to be super-soldiers, so they should be ablr to run.
