I know that SOP is designed to be compatible with other settings, so I was wondering if anyone had tried to mix them with other casting traditions, most specifically SOP with Dreamscarred press' psionics and the classes from the Occult handbook as well as the vanilla classes.
If you did, what were the good points? What were the drawbacks, if any and are there any places where the various systems may not play well, either in leaving some class/system over powered or leaving them out of the limelight?
Thanks!
