Retro had NO resume and 3 failed projects under its belt. And I doubt Nintendo feels burned by the acquisition, considering it led to the revival of Donkey Kong Country, Returns netting them over 6 million units and Tropical Freeze doing about 5 million so far across 2 platforms, along with a reliable developer to assist with other projects. All for the low price of less than $2 million plus wages following 2006.
Everything is an exception on this topic... until it's not. I have watched this goalpost get moved around since the Retro acquisition in 2006 and it's exhausting. If the devs are excited to work with/for Nintendo, produce something that makes them significant money and the pre-existing owners of that capital are willing to divest of it, it can/might happen.
@Rooster, one of these 3 conditions not being met (likely the last of the 3) is likely why it hasn't happened for others.
I'm not exactly a fan of consolidation, but I appreciate Nintendo liking employee opt-in on that before engaging in it, and I'm not about to pretend that there's some magic (and ever-evolving) confluence of necessity beyond those conditions I outlined, as though being a Nintendo subsidiary is some special exclusionary club and MercurySteam just ain't
cool enough to be part of it.
But I'm off-topic now, so I'll cool it.
