In my opinion, Xbox absolutely nailed that Gamescom.
White Xbox One Sunset Over Drive bundle.
1TB Xbox One (shame it is COD AW only)
Rise of the Tomb Raider exclusive
The ID @ Xbox trailer was brilliant and showcasing some great games. Super Hot looks very interesting.
Space Engineers
GOAT Simulator!
SMITE - Moba
The Escapists looks very old school and very interesting.
Scream Ride seems a really interesting concept
Ori and the Blind Forest looks brilliant
Halo Master Chief Collection and Halo Channel, that is how you do a re-master. Throwing in the Halo 5 beta makes things even better.
Forza Horizon 2 looks fantastic
And of course, Quantum Break.
I was very, very, very, very impressed with pretty much everything I saw.
