For some reason I just have a good feeling about State of Decay 3.
SoD2 has had incredible post-launch support, the concept has always been very strong, all the IP needs is cleaning up technically and a few new ideas. The change in leadership which happened years ago may be a good thing for the IP, sure there were cultural issues mentioned where people were being treated poorly but those were also apparently fixed as soon as Microsoft got involved.
I don't really think they need to reinvent the wheel for this IP, it just needs to be a more technically impressive game.
