The thing about modern gaming that has frustrated me most is the loss of couch co-op. Fewer and fewer games have included split-screen or local multiplayer, opting instead for online multiplayer only. I'm not sure if this stems from some antiquated idea that gamers are solitary creatures, or a half blind attempt to "connect" players. Regardless of the reason, it's excluding millions of players out there who enjoy games most when playing alongside friends and family.
The few holdouts that I've regularly been able to count on for split-screen play dwindle a little every year, and now I've had to cross off a dear old friend from the list. In an interview with Gamespot Bungie has confirmed that Destiny will not support split-screen play at all.
