UbiquitousRat is a well known blogger by many in the BRP gaming community. He's been writing about Mythras, Rodney Leary's Classic Fantasy and Mythic GM Emulator for some time now, finding that switching from Dungeons & Dragons is a blast. Not only for the GM, but for the players as well.
"Given that I am now pretty familiar with Mythras, I believe that M-Space is in itself a quick and easy game. What I mean is that, given the relative crunchiness of the core rules, this science-fiction iteration seems to have avoided adding complexity to the system."
