I play the guitar and yes it takes a long time to learn but it must have taken a while to learn how to play that game to that level. OK, learning to play an instrument would take much longer but still, the payback is much better.
People want quick fixes that's the problem. People hear me play the guitar and sometimes take it up themselves then wonder why after a few months it doesn't sound too good. Maybe in ten years they will be good.
Maybe if you start delving into the TG2 function graphs then in a few years you wll know how it works
