Thick as Thieves - TTRPGs

Long-time friends play TTRPGs!

What makes a great Table Top Roleplaying Game?
Iron-tight rules?
The freedom to tell any story?
Giving the players as many ways to destroy my prep as possible?

Join us as we embark on a story that will span many different TTRPGs, in an attempt to answer this very question.
And, hopefully, we don't get too distracted along the way.
We are Thick as Thieves.
