Pixar is working on a movie based on Edgar Rice Buroughs Mars novels. I have the old SPI board game John Carter of Mars and it would be interesting to see this produced by FFG. If they included a plausible solo play option I think it would go over pretty well.
A strategic level board game would be interesting as well, many possibilities for nations at war and role play to boot!
Of course if Pixar botches up the movie then all bets are off!
