Because they did not affect the amount of core games Sony put out in the last 3-4 years, so Move is a non factor to me. Kinect would have been the same had MS followed suit. It's really not hard to understand the concept.
Again, like anyone can see Micrsoft released it's biggest core games for it's core fanbase.
Which is why in those same 4 years the 360 has always had the #1 selling exclusive of the year.
Last year, we now know was the final year of the 360. It is the oldest system this gen by an entire year.
It is a fact, that MS supported it's core games as last year Xbox core got to play:
Halo 4
Forza Horizon (Forza name but a completely new open world racing experience)
Witcher 2
Minecraft (Xbox 360 edition) which sold over 5 million on XBLA
Trials Evolution
Fez
Mark of Ninja
Alan Wake Nightmares
Deadlight
On top of the huge releases like Mass Effect 3, Black Ops 2, and Assasin's Creed 3
The GOTY was The Walking dead.
AAA games are not cheap which is why you havent seen a New AAA Ip from Sony or MS in the last 3 years.
Who are we kidding even games on the level of the amazing Journey from a small team takes years and almost bankrupted Thatgamingcompany.
Sony and MS take the same approach to how they release their big games.
Fans wait 2 to 3 years to play the next big Halo, Forza, and Gears jst like it take those same 2-3 years for fans to play Uncharted, Killzone,and Infamous.
Sony started a year late and are ending early so now you are seeing the next iterations of Killzone and Infamous launch on the PS4 instead of the PS3.
You see in this economy what happens to companies who release new IPs like Kingdoms of Amalur.
Microsoft is feediing the core 360 gamers and the sales and hours online prove that core 360 gamers are the ones who crave franchise like Halo 4, Gears, as well as Minecraft & Black ops 2.
Derrick isn't a core 360 gamer that loves those franchise and doesnt even own a 360, so his preferences aren't going to line up with the millions of fans of those franchise and the 20 million+ who frequent Live and game daily on that console.
Micrsoft supports the audience they should but the fact is nobody is going to like every game that is released for any console that they own.
