It's not that they left , it's the way they did very unprofessional but that's the industry . It's too bad, limited to very very small contract work , and surely they didn't truly believe they would work on "original" project . I mean , it's not a secret ,the top 2 and top 20 of that cod studio made out like bandits , millions for a single year . Just like those others guys from guitar hero a freaking clone of a japanese game . The reality is those high players with very real skills can grab a big , very big , life altering paycheck by playing their cards right. And that include feeding story about wanting to change , how nintendo is limiting them , and how another militaristic fps is just what the industry need. I don't blame them i would do the same if i had their skills.
Now vision and all that , yeah at the end of the day those fps shooter everyone are so jacked up about are just two button combo gallery with barely any interaction . The "aim" button is the worst thing ever , it gave us silly name like quick sniping and other stupidity . And to me , truly honestly , anyone can do that, that's what those guys think anyway , so why not trying to do the militaristic shooter the "hardcore" will go crazy about because of some beards or location or fictitious enemies . It's big money .
Just don't go on and on about how nintendo is forcing them while they simply helped that small studio having an output at all with inviting them to do a new genre "rare"ly done by big studios anymore aka dkc , and working on mk7 of course.
