My Friday night gaming group runs what we call Casual Fridays. Basically, they're relatively short games, lasting about a month (4-5 sessions), just so we can try different things, have fun, and not have a huge commitment requirement. So, right now I'm running Paranoia, however Mongoose Games is currently between editions for the classic science-fiction spoof RPG. I have the previous edition which has no other books out for it right now, and the new edition only recently got Kickstarted. On top of that, I really don't want to learn the old version's system!
What to do...?
