I love it. I had both the original and 2014 it for 360, and there was noticeable lag. However, I recently bought it for PC on the steam sale, and there is no lag whatsoever. Definitely get it for the newer platforms or PC, since the better processor does eliminate the lag.
The positives:
- Motivates you to play more guitar
- You learn to play some cool songs fairly quickly
- Decent way to learn some basics
- Augments other training
The negatives:
- Technique can get sloppy
- Some recognition isn't perfect (chords, palm muted, bends, vibratos etc)
- To properly learn, you should probably still get a teacher
I couple of other negatives for me
It's connected via Uplay... so no Steam family sharing.
None of my DLC from the 360 transfer over (over $100 worth), so I have to buy them again.
