My wife is a forever-GM! She never really felt comfortable playing but loved to do the heavy lifting of being the GM, and she is by far the best I had the pleasure to play with. Due to her doctoral dissertation and work related overload, we played less than anticipated in recent years. That was mostly my motivation for playing solo … not to mention that there are several systems and/or settings my wife is not a big fan of.
She was always interested in what happened in my sessions but never really wanted to play herself. That changed last weekend … and she loved it!
We played (co-op) a typical murder mystery in the style of Miss Marple, Jessica Fletcher and Paul Temple. The adventure was located on the island of Guernsey in the late 1950s. The protagonist was the retired crown prosecutor, a quirky 70ish old lady from Saint Peter Port. The initial rulesystem we used was BRP because my wife is a d100-ultra and only reluctantly agrees to play something else. After the first session, she said that the rules were more a hindrance than a tool to tell the story, so we ditched BRP and switched to the rules system featured in Mythic Magazine Compilation #6 (Mythic Magazine Issue #31) “Mythic GME as a Rules-Light RPG”. Best decision ever!
The hook was, that our character’s plan to have some nice scones in a harbor cafe got interrupted by someone who asked us to move our scraggy bum to the LaValette Garden. Oh, btw. we used an original map of Saint Peter Port from the 50s.

As we reached the park, our character found the famous pelicans inhabiting a small pond, paddled to death. Hmmm … that sounds like a case. And what a case it was: interviews were made, lies were told, threats were made, and the tires of our bicycle were pierced. That was quite annoying because we were going to chase a suspect.
This was my first time playing Mythic GME co-op, and I (we) had a blast! You should absolutely try it. Oh, and because I wasn’t motivated to use my regular solo setup, I quickly downloaded the app (Andoid, iOS, desktop) and bought the extra content. What a glorious piece of software that is … the only thing missing was the Mystery Matrix.
