Gotta say, as an Xbox player (well primarily Xbox) I really am glad that Microsoft stepped up their presentation this year, so I just gave my vote to them.
But there are so many games I'm excited for- Fallout 4, Kingdom Hearts 3, Star Wars Battlefront, Mass Effect Andromeda, Star Fox Zero, No Man's Sky, Final Fantasy XV, The Division, Rainbow Six Siege, Ghost Recon Wildlands, Halo 5.....
just to name a few.
