I talked a little bit about my experience running the SotM demo game with Andy, Ian, Russ, and Peter over the course of the day afterward, but I'm still not comfortable with how I handled a couple of things and am still trying to figure out what I might have been able to do differently.
Background: The people for whom I was running the demo game were a family, two parents and a girl who was probably in her early teens. The kid was in a furry costume for much of my interaction with her, which initially made judging her age difficult. The father said something that suggested 12, but after she had pulled the head off later on, I still think my instinct of 13 might be closer to right. The parents expressed some interest in learning, so I grabbed my big bag of SotM and we went looking for a place to play. (Eventually, we ended up in the same room as where Platinum Warlock was running a CSW game. PW, I know that you were busy with your own game, but if anything jumped out to you, let me know.)
Game scenario: Baron Blade (because training game) vs Legacy (me), Tachyon (kid), Wraith (mom), and Bunker (dad) in Ruins of Atlantis (their choice).
As we got into the game, it became clear that the teen wasn't entirely focused. I think that some of that was being hot under her furry suit, but it later also seemed that some of was connected to her being overtired and some was that she was a video gamer at heart. (I did subsequently make a point of trying to plug Sentinels Digital afterward.) OK, I can deal with that - I deal with partially/dis engaged teens in my day job all the time. When I run teaching games, even for my 5th grader & his friend, I have two things I consistently do in service of keeping their immersion and agency. One is that during a player's turn, I'll prompt them along the lines of "Tachyon, you get to play a card. Tachyon, you can use one power now. Tachyon, draw a card." The other is that, if asked for suggestions, I will try to explain clearly what options exist, sometimes identifying that these are what I think are the best two or three options of more than that, but ultimately leave the final decision up to the player.
One thing that bugged me, and that I didn't feel like I had a way to intervene more directly, was that the dad kept pressuring the daughter to pull her furry head off. He kept arguing it from the perspective of making it easier for to interact with the rest of us, but despite some of his behavior in the public area of the con, I couldn't shake the feeling that part of why he was going it was because he wasn't comfortable with her identity. The best I could do there was just to say things like, "I'm not having trouble hearing her." It felt like any more direct intervention would have been interfering in a family dynamic that I had no place interfering in.
The other thing that happened was that about 1/3 of the way into the game, we had somebody come by and start to watch what was happening. That's not an issue - we're at a con; we should expect to have an audience. He started to offer "help" - also something to expect. However, the help he was offering was much more in the vein of "you want to do this" than "these are your options and what will happen if you pick each." Shortly after he had come over was when it became really clear the teen was having a hard time focusing on what we were doing, and so I didn't directly ask him to let me handle teaching the game. But, despite my saying at least twice that I was trying to do this, rather than what he was doing, he didn't take the hint and continued to try to quarterback the rookies' turns. I suppose I could have asked him to leave, but as I didn't think we was engaging in behavior that rose to the level of "alert con security," I wasn't comfortable doing that, either.
The game ended in a victory, and the parents definitely thought they had a neighbor who would love it. The dad was interested in playing again sometime, as he was starting to see how the pieces came together (getting a 20-point Omnicannon shot off probably helped); the teen might come around to it via the app eventually. (Earlier in the day, I also helped use the app to teach a father/son who were waiting for somebody else in the family to finish something else. He came by and thanked me later - I think he had a really good time with it.)
I think I'm especially sensitive about this right now in part because I just finished reading a long, and depressing, piece about how tabletop gamer culture has a major problem with harrassment, racism, and rape culture. (I agree with much of said article.) I've also got a daughter in kindergarten who is one of my main gaming partners, when she & her brother aren't busy fighting about who gets to play Minecraft.
tl;dr - introduced two families to SotM card game, one via app & one via physical game. Had issues with how dad interacted with daughter over furry outfit wherein I wasn't comfortable with interaction but was more uncomfortable with intervening. Also had issues with a passerby "helping" (almost?) to the point of taking over at least two of the new players' turns. Maybe should have asked him to leave & let me teach the game, but didn't.
