I only had the best experiences with them. Both as a customer and licensee!
I feel I need to clarify this.
I bought the original first edition and pretty much all the books they had out at the time, but didn't really get around to playing it.
Soon afterwards they came out with a revised edition with some minor changes in the rules. Having just bought the books I asked what the changes might be.
Their answer was: "You have to buy the new books to know."
They lost me right there. As far as I know, the differences amount to a few sentences and wordings, so we're definitely not talking about a completely new edition here.
