How does your system handle creature capture characters? Like Pokémon. I was thinking about Rallen from Spectrobes.

We do have some characters that own Pokemon already, so we're definitely accommodating. There are often opportunities to get creature-capturing supplies, especially when I'm setting up areas where such characters will be hanging around, and I can include specific creatures when worldbuilding for your areas. In terms of progressing captured creatures, like getting Pokemon new moves and evolving them, I'm pretty laissez-faire. You can progress them pretty loosely, with them learning new moves every few fights if you want, or evolving after a big story event. If you wanted you could level them up like mini-characters, too, so really, whatever makes sense and feels fair.
