I will seriously LOL if multiplat PS360 games have NO advantages on the WiiU because devs are lazy.
Oh, that old chestnut: "The devs are lazy."
Borys, when you go to work each day, do you just do whatever you want? Or does someone have some say over what you do with your time? Even if you are self-employed, you probably have customers, right? They have some say over what they expect from you, right?
Developers are the same way. Bosses outside of the development department tell us what to do, and frequently licensors tell them what they want the devs to do. It's rarely negotiable in the former case, and almost never negotiable in the second, particularly if the license is a well known brand or property. And the bottom line is, it all comes down to an ROI report, which frames the entire scope of any development effort.
