The "Play or Do" language kinda loses me. I'm not sure whether it should mean looking to give, receive, lead, follow. Or could it mean interest in finding a partner character(s) that have that attribute, or are involved in the same. Likewise, I just don't know how to read "Partner." None of these are very relationally clear.
Also how about just watching/associating with others in a story where that happens? Maybe we have a lot of emphasis on 1-1's where that isn't a factor, but I wouldn't rule it out. And it could be useful in assembling groups where something "must be part of the story" but not all will necessarily participate.
