I just had a thought for a new game I want to run that is similar to Rime City from Detective Pikachu. Where everyone (not just trainers) have a single partner Pokemon that is theirs.
I would want this Pokemon to be only loosely under the control of the player but still in general useful and on their side. I was thinking of running it as a superhero game like masks where the "superpowers" are really just their Pokemon but that doesn't feel right.
Does anyone have any idea of a good system for this kind of thing. I've looked at the few fan Pokemon systems and while they work well enough, they are really designed for the standard "gotta catch em all" mindset which is something I really don't want to go for.
