All 3 of those especially the 3rd have been improved this year, they removed all the old celebration cutscenes and now celebrations are all done in real time. The crowd and sidelines have improved too. I know some people have said on here that the sidelines weren't touched but that is not true, the players now respond and watch the plays on the field, come off the bench to congratulate teammates, get upset and frustrated on negative plays. The crowd responds properly to big plays and stands up and cheers during them as well, crowd models have more indistinguishable character models now as well, not as many duplicates. Rex has said they aren't there yet with the Living Worlds feature but improvement has been made since last year in that area. I don't know if this is considered living worlds but players also will look up at the jumbotron on big breakaway TDs.
