Xbox One is now backward-compatible with the 360 library. Now to figure out what to do with the potential empty shelf space.
Halo 5: Guardians - Hard to ignore a Halo and an expanded 24-player multiplayer experience will make a significant difference. Due out Autumn 2015.

Ubisoft, the other global major publisher with a stable of big franchises, came next. Most of the line-up was somewhat expected, though the new super-hero themed South Park game seemed like a nice surprise. Hopefully it's as good as the Stick of Truth.

Sony were the last big dog on the Monday. A sigh of relief surely went up when The Last Guardian finally appeared, followed by interested humming noises for more Project Morpheus info.

Uncharted 4: A Thief's end - Gameplay video shows a classic chase scene, from running through a city to cutting cross country and ultimately up onto the rooftops.

Horizon: Zero Dawn - New IP alert! The Killzone gang, Guerrilla Games, launch a far future 3rd person adventure game featuring nomadic humans and enemy machines. Looks interesting.
Final Fantasy 7 HD Remake - It's easy to get jaded with all the HD remakes these days, but FFVII is perhaps one of the great big adventures of a certain generation, a game that for many defined their Playstation 1 experience. The game looks great, so here's hoping Cloud retains his charm.
