Thanks for the recommendations, Mortal Combat for sure and Limbo sounds cool. I've often heard/seen the Humble Bundles in threads here and on Mameworld, but as I wasn't purchasing anything game related, I didn't realize it was on Steam. I'll join the herd, just a little late I guess.
As for the different versions of Rocksmith, I can't really compare them. I only played the Xbox 360 version for a short while, and like I said, I may not have been as coherent as I normally am

. That being said, I can never seem to be able to navigate through menus on modern gaming consoles, so when it was time for a new song or "guitar arcade" game, my buddies handled that. My honest opinion is that Rocksmith doesn't actually teach you the guitar. It'll teach you how to play songs, chord shapes, and scale patterns. Where it falls short is it doesn't tell you what notes are actually in the scale. That is, it will show you the shape of a scale, say Am pentatonic, but not what the individual notes are in the scale and where on the fretboard it is. From what mini games I've played, the scale was simply the pattern of the common "blues" scale on the 5th fret, not the whole fretbord, like this;

I really enjoy the game, and I know I've just begun to scratch the surface as to all the lessons and tutorials it offers, so who know's, learning the fretborad may be in there. I really don't think there's any music theory in there, though. As for making practice a lot of fun, it nails it.
So you want to really learn, here's how it happened for me. I had the music classes in High School, was a drummer in the marching band. My brother bought a cheap Harmony acoustic guitar at a yard sale and never played with it, but I did. I read the Mel Bay books, played Smoke on the Water, learned the "four chords" so I could fake a lot of stuff and had friends who played in various garage bands. I was, and still am, the electronics geek, I was forever repairing amps, gear, and when I was in high school, a lot of 8-track players ( I'm old ). I ran sound and lights for a bunch of the guys and really just through osmosis, I picked up a few things, and a lot of bad habits. Years later, I met who would become my best friend, Ed. I decided to buy a cheap electric guitar and start playing again, the damned thing would not stay in tune. I went to a local music store where I met Ed and he explained correct guitar setup and intonation. Being the gearhead I am, found it fascinating. While I was there a kid came in with an old Fender Princeton with a bad hum. I took it in the back of Ed's shop and repaired it. We were in it together after that. Ed had been playing bass for local bands, and I'd go out to at first see, then later haul gear, run sound lights, and repair. After the bars closed we always seemed to end up back at Ed's shop with half the bar, to continue playing, and having fun. That's where it really happened for me. Different people showing me how they did it, and having these impromptu jam sessions.
While I see the need for individual lessons, and private study, the real learning experience comes from playing with others and that's not something I think Rocksmith can do.
Thamks,
Scam
BTW just figured it out tool/options/play settings/invert strings now it looks right to me.
