our final play session was really something, we ended up solving a fairly sophisticated puzzle while split into three groups, with pretty good radio discipline and remote signaling and all the rest.
still some PTT issues and a few "over"s that didn't end the message, but a far cry from our early play sessions where we had comms conflicts and did a lot of disorganized wandering around!
a lot of funny moments where stuff that seems obvious to me (because of exposure in scouting) was not something my friends were thinking about until the problem dawned on them or somesuch. and real orienteering and collaboration skills were developed in the process!
