Rocksmith is extremely engaging for any musician of any level and a pretty good training tool in its own right. There are some things that make for a less-than-ideal training environment by being too cludgy (like the riff repeater and passage accelerator trainer) but all in all it will definitley make anyone willing to put in the time a solid guitarist. You will get out of it what you put into it really.
Due to licensing issues the song list is more skimpy than I'd like (there are notable omissions that ought to be no-brainers like Led Zeppelin, Pink Floyd, Jimmy Hendrix, ACDC, etc.) but most of what's available is pretty good.
