Recently I saw that thing - Grimm, and was impressed by the book cover illustration, and started to search for some more info on this strange little book. Now I read the forum and have read the old horizon-ff book. I have to say I very very liked the idea, it's like the move Grimm Brothers.
I really enjoyed all interpretation on Grimm characters and the idea of the book, but I found a little problem - all people I play with are let's say mature and over 23-24 years, and don't seem to find playing "childs", especially some strange one-time system entertaining. On the other hand, I think Grimm can be used like breath of air between long campaigns or when there are people lacking from session. If you faced similar problems, what you think is the best way to approach my players?
