James Mathe's passing was brought to my attention earlier today, but with our own, in house mourning (my parents' cat passed at 315 this afternoon at 18 years old) I haven't been able to settle in until now.
James is probably best known as the creator / original owner of RPGNow. I remember when RPGNow and DriveThruRPG were competitors. I always leaned towards RPGNow back in those days and did so even after the merger.
James' self-written bio is linked below:
SUMMARY: I have pioneered 2 new industries, own 5 companies and 3 game stores, completed several dozen successful Kickstarter campaigns, and host regular game designer events/conventions.http://www.jamesmathe.com/bio/
