I've spent around 120h in Destiny and I still have to say, that lacking split screen option in coop-oriented game is a cardinal sin. I'd love to spend more time in Destiny's universe, but whenever my wife's coming we just have to switch to another game (and that's probably the reason why games like CoD, Minecraft and FIFA almost always are way ahead of Destiny in activity charts).
Bungie, please, PLEASE add split screen in Destiny 2, so people who live with families can create fireteams too!
