SNW he's had the least amount of input. He's given a credit for story but thats it. This could change in the future. He's had way more input in STD especially in the first season and it shows. He doesn't get star trek he gets star wars. Let's just admit that.
Please cite a source for the idea that he’s had the least amount of input on SNW. I’m going to bet either you can’t, you won’t, or you’ll tell me to Google it myself.
