I don't care
Halo was known to have great couch co-op. For those of you who didn't play halo Couch co-op is where you and a friend and/or sibling can play the story while sitting right next to you playing on the same system and tv. Not everyone's family's have a crap load of money to buy 3 Xbox Ones or PS4 so that you can play with your brothers or sisters. Do you think that Destiny should have Co-op?
Totally agree with local co op compatibility. Not only would they get more sales because very few games offer local co op and alot of people still like this feature its cool and fun. The game would still be played the same and also people aren't bound to playing online and can be offline and still play which is alsk better cause you might not want to be online all the time. So indeed please add this in.
