I used to run a weekly Tuesday night GURPS Fantasy and a Friday night GURPS Traveller campaign for a couple of years, but the sheer amount of prep work due to absolutely NO support from SJG forced me to switch to Pathfinder and Starfinder. It's a pity because I really do prefer GURPS. And the ironic thing is, I was buying up GURPS products from SJG regularly when I was running those campaigns, and I haven't bought a GURPS product since. SJG is missing out a quite a significant revenue stream IMO.
