Microsoft have revealed the launch lineup of Xbox One game today with 23 titles scheduled to be available on the system. The actual launch date itself wasn't revealed though. Here's the list of what you'll be able to buy Day 1, with the co-op titles in bold and linked. Rumored co-op titles are italicized.
Assassin's Creed IV Black Flag (Ubisoft, Ubisoft) Battlefield 4 (DICE, Electronic Arts) Call of Duty: Ghosts (Infinity Ward, Activision) Crimson Dragon (Grounding/Land Ho!, Microsoft Studios) Dead Rising 3 (Capcom Vancouver, Microsoft) FIFA 14 (EA Sports, Electronic Arts) Fighter Within (AMA Ltd., Ubisoft) Forza Motorsport 5 (Turn 10 Studios, Microsoft Studios) Just Dance 2014 (Ubisoft Paris, Ubisoft) Killer Instinct (Double Helix, Microsoft Studios) LEGO Marvel Super Heroes (TT Games, Warner Bros. Interactive) Lococycle (Twisted Pixel, Microsoft Studios) Madden NFL 25 (EA Sports, Electronic Arts) NBA 2K14 (Visual Concepts, 2K Sports) NBA LIVE 14 (EA Sports, Electronic Arts) Need for Speed: Rivals (Ghost Games, Electronic Arts) Peggle 2 (Popcap, Electronic Arts) Powerstar Golf (Zoe Mode, Microsoft Studios) Ryse: Son of Rome (Crytek, Microsoft Studios) Skylanders: Swap Force (Vicarious Visions, Activision) Watch Dogs (Ubisoft Montreal, Ubisoft) Zoo Tycoon (Frontier Developments Ltd., Microsoft Studios) Zumba Fitness: World Party (Zoë Mode, Majesco)There are a few surprises of games we haven't heard are getting a "next-gen" release, LEGO Marvel Superheroes and Skylanders come to mind. We do know Call of Duty: Ghosts will have some sort of co-op mode, but it hasn't been talked about yet and we heard some rumbling at E3 that Dead Rising 3 would also support co-op.
Either way it looks like a fairly solid launch lineup, but the launch lineups are never the issue. It's the wait until the next batch of games that usually ends up being a problem. If Microsoft doesn't have a solid, steady stream of titles over the 6-9 months, it could definitely hurt the system as we saw happen with the Nintendo Wii U.
