Happen to own the Pathfinder version. Even if you don't like the setting that comes with Neverwhen, it has all of the mechanics and tools you need to play nearly anything in your favorite system. Steam punk, sci fi, modern day. If you liked the setting for Shadowrun or Star Wars even you can use Neverwhen to adapt the setting to a d20 system of your choice. IF you are a fan of the old spelljammer stuff that no one can get updated, this will allow you to play in one of the current systems. I have players that can be very picky about even trying new systems. They like the ideas behind different settings but the change is system seems to really bother them. As a result, I use Neverwhen and port any setting I want into the system they are willing to play.
