I think the Fender Play stuff is really good at getting you to playing stuff that you can recognise as quickly as possible, which is great for keeping your motivation up through the early stages of learning an instrument, which frankly suck arse.
I don’t think it really gives you strong fundamentals to then go off on your own and build on, though. The bits I did had next to no theory or explanation of stuff, it’s just “let’s get you playing ZZ Top riffs as soon as possible”. Which is good for the reasons above! But then I wanted something broader, and that’s where the other stuff came in.
