Of the PRPs I've been in the last few months, some have been great while others have left me feeling like I wasted my time.
And there's definitely one thing that stands out as to 'why.'
In the ones I enjoyed, the ST made an effort to engage everyone. No one or two PCs stood out above the rest for the duration of the scene. In the ones I enjoyed the least, there was usually one or two PCs dominating the whole thing: jumping up to make every roll, rushing forward to the point of ignoring others who might have input or skill that'd be of benefit, etc.
I absolutely blame the latter on the ST. Not in a malicious way, but, as an ST you should be able to tell when people are steamrolling and do something to get things more in hand. Be it paging them quietly or taking a firmer grip on the reins as you guide the scene.
Now, it's easier (as an ST / IMO) to take the reins when you can see peoples' sheets. Instead of 'Whoever can, roll Medicine to...' you can page Bob, the medic, directly and ask him to make a roll.
Some STs ask for feedback after a scene and when it's been one of those where people are steamrolling, I find myself a little... unsure how to approach that feedback. In part because I want to be able to provide some constructive advice. Instead of just 'Well, unfortunately, I felt unnecessary because other people were always too quick on the draw to roll or volunteer without consideration for sharing the spotlight' I want to be able to provide advice.
So, STs:
How do you make sure to engage an entire group and provide interaction for everyone*? What advice would you give for someone just learning?
*Before the usual naysayers jump in, I don't mean the players who don't bother to engage in return. I mean the situations where players who want to engage are constantly left out because someone else is quicker to hit enter. Those times where you get a page from someone going 'So I want to try X, what do I need to- oh, never mind, I see Jane already did it.' These people clearly want to engage, but are being left behind because they're not as quick on the draw.
I'll mull over my own methods and write up another post in reply, but I'd love to see what others find works for them.
