While Japanese Xbox One's sales are face down in the dirt, it apparently isn't due to the machine not getting a fair shake. During the 2014 Tokyo Game Show, Microsoft's booth was jumping on both media days and public days. Gamers crowded around screens, waited in lines, and in general had to snake through a crowd to get anywhere in the big green zone.
Microsoft had primarily Xbox One titles on display, though several are cross-gen with the 360 and/or PC. I played Sunset Overdrive, Ori and the Blind Forest, Resident Evil Revelations 2, D4, and more during my time in there.
