Take a look at the last time this mod was updated man, long dead. Speaking of which I should probably stop the notices for discussion posts...

I actually got it to work on a Mac running Yosemite 10.10.3 and only the BNW expansion. Check out the forums and instructions I followed. It all seems to be working really well except for the Stark Civilization.

I appreciate the heads up but I've had it working previously. You'll likely find that once you progress to a certain point (I believe it's when you research banking, tough to remember) the game will not allow you to advance your turns. I and many others had this issue ages ago, and as you can see the mod has yet to be repaired (updated) in regards to that game breaking bug, or the several others I've seen listed.

I did actually hit that problem yesterday while playing. It kept telling me to choose production but it wouldnt open up the screen to actually choose. It is a shame that an awesome mod like this is borken. It would be nice to see it updated; especially since I basically bought BNW just to play this mod. But Civ5 is an amazing game anyway so it was worth the purchase.

Totally agree man, but all is not lost. The author of this mod has stated he is working on a new, "vastly superior" GOT mod for civ 5. I dont know much more than that but its something. BNW is a great expansion,with or without this mod definitely agree its a worthwhile purchase

Any word on when the "vastly superior" GOT mod will be released?

bump

I had completely forgotten about this, nice bump. The most info I have at present is on this link http://forums.civfanatics.com/showthread.php?t=498600&page=4 where there are posts by "Luir" who is called Fairfax on the forum explaining hes working on a new mod. I'm not connected in any way to the authors, just happened across that, probably more out there on this but I don't have the time at present to go hunting.

Nice, thanks for the info anyway.
