Easier to just host a party or meetup where you can over invite and if some people don't show up it's no issue.
He is trying something different now, to make a hybrid campaign where there’s a lot of one-shots in a broader story arc. It’s structured like missions in an ongoing struggle.
Maybe if you want to do board games, we need more games that scale up and down easily. I’m not a board game person, IDK.
Party games: Scale well with more people, easy to explain
- Werewolf
- Werewords
- Codenames (favorite)
Beginner Games: Accept a decent amount, somewhat easy to explain
- Camel Up
- Flip 7
- Dungeon Fighter
- Ticket to Ride
Games that have nothing to do with your problem, but I just wanna mention:
- Everdell: Cute critters prepare for winter
- Root: Cute critters prepare for war
- Azul: Place fancy tiles that look and feel delicious
- Bohnanza: The best part of Catan without the bad parts
One thing I do that helps is get people to RSVP with a specific arrival time, and do my best to have a game about to start around that time.
If you show up unexpectedly, then I'm not going to feel bad about you sitting out for an hour or more.
People unexpectedly bringing a partner/friend who is not really that into board games is the absolute worst thoguh.
You're trying to arrange the wrong type of event. A board game group plays a variable number of games simultaneously to accommodate the number of players each game can support. A board game group does not try to fit everyone into the same game as a matter of principle.
We've been having ongoing games (around 2 going at every one time) since about a year now I think.
Still do in person games as well, but this at least keeps that group going through in-perwon drought periods.
Now, I host meetups which typically get 8-15 people and multiple games, so an unpredictable player count is not an issue.
