Geek Native’s already dug into the differences between the Firefly RPG and the Serentiy RPG. We get it; different companies issue the rights. It also seems clear why so many fans don’t get it or don’t care to get it. We’re talking the same mythos. We’re talking versions of Cortex.
I suspect this will be an on-going conversation Valentinelli and MWP have with fans. As long as the game sells there shouldn’t be any bother.
The other questions help a little more. It looks like Margaret Weis Productions will get to grow the canon. Here’s a new question? Will that tie in with Dark Horse’s new Firefly series?.
