Well said.
I fear Westeros doesn't lend itself to action RPGs -- most likely not to CRPGs of any sort -- and certainly many of the elements that make the novels so powerful and engaging would be utterly lost in that medium, no matter how well written. So... much as the idea appeals to me... I can't see Game of Thrones translating well to Skyrim at all.
That said, if such a project was started up seriously, I'd follow it with interest.
elderscrolls is NOT
just an action rpg. the game is not just about killing and gaining experience and gear, even with that said this series does lend itself to an action element because of the many battles that take place on behalf of the houses.
ALSO as a matter of fact the
non action element could be handled much like the great houses in morrowind, complex factions and character development are not impossible for an elderscrolls mod, they are just difficult because of the scale. however due to the popularity of the series, i doubt you will have trouble getting people to want to voice these parts and work on this project. good luck, if i have any free time, ill be glad to lend a hand to the project if it gets started.
