I've corresponded with REM since he was laid off from WotC (not long before the Dungeon 88 adventure was published IIRC, perhaps in the Christmas 2000 layoffs?? [I could have my year wrong there]).
Anyway, Roger has tried to move into mainstream publishing. He sold all of his gaming stuff. He quit the industry _and_ gaming, from his commentary; he wasn't interested in being interviewed or answering fan questions, even about his own materials. (He wasn't impolite, quite the opposite, in fact; he just wanted to close the gaming chapter of his life I guess).
