2) Phil was a devoted prankster and hoaxer. He loved to demonstrate that he was smarter and more clever then any of the people around him, and then laugh at them when they didn;t get his jokes. An example of this is "Ebon Bindings", which he wrote after being told that he knew nothing about the esoteric and occult by three of his early gamers - these were all active in the then-infant occult scene in the Twin Cities, back in the middle 1970s. See also the history of Llewellen Publishing and the Bonewitz brothers, Ike and Doc. EB is the result of Phil going into his collection of medieval South Asian manuscripts, filing off the serial numbers, and publishing the thing. He was delighted when I told him that a congregation in Illinois had burned a copy of the book, thinking it was a real grimoire, as it meant that he'd hoodwinked the gullible.
3) Phil had a nasty habit of liking to push people's buttons and rattle their chains. Once he found what he thought was a weakness in somebody's personality, he'd play on that to influence and control that person. It is, Dave Arneson told me, one of the reasons why Dave lost interest in being Phil's publisher; Dave nominated Phil for Mike Stackpole's GAMA "Hall of Shame", and Phil got the award for "Most Difficult Author In the Game Industry" at an Origins in Detroit; I still have the 'Ralphie', the statuette that Phil got, as I had to get up and give the acceptance speech.
