I guess the Marketing as Tool for that Budget was hard, considering Marketing sections of Publisher tend to be cought in the old ways. Can be seen very well looking at the Medieval realistic RPG Kingdome Come: Delieverance. On their Odyssee to find a publisher they were also hitting a wall when the Marketing didn't know how to sell a game without dragons and Magic. I guess same thing happened for Rocksmith "wait its with guitars but a tool? yeah we dont know how to seel that...give it game aspects and we can ride the Guitar hero with real guitars train to town".
