So I had my first Shadowrun session... back in September (they're once a month). Since then, we've repeatedly had players who couldn't make it due to work and other obligations (which are understandable). It's a 6 player group, and I want at least 4 to run it. As of now for December, I will already be down to 4, as long as everyone else shows up.
One recommendation, which I've had no free time for, was to have a few one-time sessions for smaller groups when this happens, so that we still play something. I've never built my own mission from scratch (though I'm going to have to start soon), and as such I was wondering if anyone had any suggestions for quick missions I could do with a small group, whether it be something one of you other GMs have done, or just general ideas for creating my own.
Anything would be appreciated.
