Nice, but a little hard if you don't yet have chords associated by name and I'm missing background music/tempo to keep track.
Personally I'm really fond of the Rocksmith game for learning guitar. It's like Guitar Hero, but with your own real guitar (and interactive lessons). I have no real ambition (or talent) for playing musical instruments, but somehow it lets me enjoy music interactively at my skill level while also giving the gratification of game progress. https://www.youtube.com/watch?v=JDQ_U3lukAQ
I have the pro guitar and played with RB3 before Rocksmith - Rocksmith is an order of magnitude better for someone who is still learning (and I think that's 90% of the target market).
The only advantage of RB3 is the ability to play together with plastic instrument aficionados, but the unforgiving implementation of the real guitar experience just made it not fun for me.
Maybe try Yousician, I used their Android App before I stumbled upon Rocksmith. Didn't play it for long but I think it will be more suited for kids. I believe you can get a half hour of free practice every day and unlimited when buying the Pro.
