For my tastes in gaming the Xbox brand has offered little.
Xbox - average console that had some games I liked, but overall paled compared to PS2 and Gamecube for me, still a solid debut in many respects.
Xbox 360 (1st half) - Good console that seriously made me reconsider many things with Sony's price and making a strong effort to appeal to me so kudos here.
Xbox 360 (2nd half) - Horrible system for me with a focus on shooters and Kinect. Almost a negative system with barely any games I wanted that were not available elsewhere.
Xbox One - The single worst unveiling of a console I have ever seen and really put Microsoft in a massive hole. All the back peddling is fine, but unless they pull a 1st half of 360 the whole time this system is DOA to me.
I don't blame Japanese gamers because as someone who prefers Japanese games I can completely see why the Xbox failed, the 360 did okay and then fizzled out and the X1 is not generating any excitement. Microsoft made a decision to focus on where it is strong, fine. The consequence is where it is weak will only create more disparity in markets. I don't see it as a shame and selfishly for my gaming interests want Sony to finish first and Nintendo second. Until Microsoft makes games I want I do not care about them as they really don't care about me.
