With my SMP players, I gave them a 13 page, wet your appetite, section of Character Law. Their response has been nothing worse than, "Cool. I like this." All said they were going to sign up and dload the beta. I won't know until this weekend. They have also been looking through the RM2 and RMSS/FRP printouts I have in ring binders. However, I don't think they want to try RM yet as the SM campaign keeps us pretty busy for two 4-hour sessions a week.
However, now that they have learned how to stop an Enigman Planet Swallower from swallowing a planet, things may get a bit freer with trying RM.
Will let you know you more if it dawns on me.
