Releasing a game on Xbox is what I call 'working with'. How would you know, Microsoft might be so pleased with the products they deliver that they over billions of dollars to buy the companie.
This is not a prediction, just a reminder of the past.
Insomniac Games are what you would call an independent developer. They like being independent. It's freedom, that's what it is. Companies like Sucker Punch, Media Molecule and Naughty Dog are first party developers for Sony. Which means everything they do goes through Sony and onto a PlayStation. And each and every one of them WILL be making PS4 games as Sony call the shots for these developers, and they said that they will all be working on PS4. So expect some PS4 games from Media Molecule and Naughty Dog.
But Insomniac are a different story, and they are proud of it. Insomniac never agreed to be run by Sony or anything like that. Sony supported them with their games, and would own the rights to their creations, but Insomniac can walk away and do other things for other publishers as well.
So for many many years Insomniac have been searching for a way to get some good AAA games on PS3 (and maybe Xbox) without Sony telling them what they can and can't do. Sure Insomniac and Sony get along great, but no one likes being told what they can't do.
So Insomniac, this independent video game developer found a way. A way to get games on both platforms without the hassle of having the publisher (and also the person who I assume would do a bit of marketing and investing) what is this remarkable new way? EA!
EA Partners will help Insomniac out by shoving the new IPs (because all their old ones were owned by either Universal or Sony) onto other platforms and let Insomniac control the whole thing! I don't know the specifics, but Insomniac remain their own company, and can own their own games! Dor once they are free!
So they have experience with PS3, and they would be stupid to turn around and work with something less powerful than a PS3 (because it would feel degrading or something) so the wise decision is to either make games for PC, Xbox or a portable device. I mean really what would you chose?
Portable devices have their ups and downs, look at how shaky the Vita is doing, JUST LOOK AT IT! The best decision would be to expand to a console almost identical to Sony' PlayStation. The Xbox 360.
BUT HOLD! Microsoft OWN the Xbox, and all of it's games too right? Well you could say that, after all it's their platform and all. But they sure as hell can't manipulate the companies making games for them! Just like Sony, Microsoft would have their first party devs, that do whatever they say, and show off all sorts of features. But the independent developers can do as they please, as long as they don't do something stupid, like put a destroyable Xbox in the game.
Of course I'm not a developer for either of those platforms, so I can't say I know all the details about these agreements, but Microsoft do NOT own the independent devs, and they would never EVER EVER be able to buy out Insomniac Games. Insomniac LOVE what they do, and they love being independent, they've made it crystal clear.
I really hope you get what I mean. The gaming industry is not all as simple as you think. We have those legends like EA partners and Insomniac Games, that will always help get games out with us, the fans in mind.
Fuse is Insomniac's own work, and it's got Insomniac Games written all though it. Give it a go, and you'll know exactly what I mean. It's funny, there are lots of explosions and the guns are straight-up EPIC!!
