Huh. If true, that seems like kind of an odd choice to weight the references so heavily toward one particular property. Feels like in 2.0, there were many different shows/games/movies/pop culture things being referenced. On the other hand... no one player is familiar with EVERYTHING they might reference. So if you know GoT well, then those references would stick out, and it might seem like there are more of them then other things, whether there are or not. Hard to say for sure.

Of course, I can't weigh in on the actual number of GoT references, since I wouldn't be able to spot them. I found both the books and the show to be dreary, bloody, overly convoluted, dark-and-edgy-for-its-own-sake rubbish. Didn't get very far before figuring out it just wasn't for me. So most references to it will just go over my head, and I'll have no idea it even is a reference unless someone told me. Until I read this thread, I didn't even know there were any references to it in the RDM storyline.
