Rocksmith 2014 has been compared to Assassin's Creed 2 by creative director Paul Cross.
In a gamescom session attended by Digital Spy, Cross said that while the original Rocksmith had some good ideas, it wasn't fully realised.
"Rocksmith was released in the US two years ago, with the sole aim of teaching people guitar and bass," Cross explained.
"It was pretty good if I say so myself, but we made a few mistakes. It wasn't perfect.
"We like to think of it as Assassin's Creed 1, which had some awesome ideas, but wasn't fully realised.
"So Rocksmith 2014 is our Assassin's Creed 2, where we go back, look at all of the feedback, understand all of the things we did wrong and get to fix them."
