We didn't really use it all in our first playtest.
In fact we found the text describing it VERY confusing. Have another read of it and tell me, can more than one player have Inspiration, or is there 'one' that is passed around?
I assume several can have it, but that makes it weird on the whole give it to someone else.
In any case, we might adopt a similar system we use for Savage Worlds Bennies. We have white poker chips for RPing. These are spread around so everyone can hand them out. A player receives one for a good RP moment. When they get 5 they cash in for a Blue chip which is a Benny. (In our case Inspiration).
Of course, of the player does something REALLY cool or acts out a flaw for eg, they go straight to the Benny. This is rare, but happens. I think I will try this system with Inspiration.
So, to anwser own Q, I will give out more than 1 Inspiration.
