Suspension of Disbelief by Alex Schroeder.

Suspension of Disbelief by Alex Schroeder.
This is a German article about why he randomly rolls treasure. I thought this might be interesting for solo players, too. (Edit: see English article below.)

Here's my (loose) translation of the most important bit:

"When I [the GM] randomly determine monster treasure instead of deciding it [beforehand], I can feel as if we explore an unknown, autonomous world together instead of just experiencing a pale imitation of my dreams. It's easier for me to believe that my campaign world "really" exists."

Then he writes about the illogicality of random results and says that there are 2 ways he handles that:

a) see it as a challenge to incorporate it into the world (be creative within the constraints of the dice rolls)
b) don't slavishly follow your dice results

The choice of what tables to use is a creative act in itself.
