Inspiration in raw DND is extremely under baked. Bg3 expanded it a little by letting you hold more than one, and actually using it. Most tables I’ve played at don’t use it, or it’s pretty rare.

Fate by default starts you with 3 fate points per session. It expects you to use them and has clear ways of getting more.

I really tried to get my old DND group to use then more, but it didn’t really click. I wasn’t a good fit for that group really.
