Update: my Tuesday game night went from 5 players to 2 in about 4 months
Everyone in our group got into heavy euro games with 3 hour teach times, so the casual folks just quietly stopped showing up. Now I'm wondering if I should split it into a light night and a heavy night, or if that just kills the whole group?
Tbh I once tried to teach my wife Terraforming Mars and she fell asleep before the rules explanation even hit the halfway point, so I feel your pain. Splitting into two nights could work but you might end up as the only guy dragging a heavy box to a table for one. Maybe try a monthly heavy day once a month and keep the regular night light, that way the casual folks have a reason to come back. Two players is still a game though, so you're not dead yet.
