Although there are plenty of MC variants scattered around the other two sites, might it not be appropriate to use one of the two available slots in here for a new one? We only have the Long Game. Perhaps an Imposters version of some sort ... like Literary giants? Or an old classic that I'm not aware of.
Hmmm rab .. I think I'll wait to see if there's any support for my idea, or even an alternative suggestion/theme, eg. a couple of weeks ago, Huxley mentioned [in MCiOS?] the Worldwide Underground Station map which drew some favourable murmers. Mind you, I haven't seen him around much lately.
