I'm tailing back on my gaming too. I'm 33 and I like to try different games. There are only a few that I stick with though. I've got a job that takes all my focus, games are a nice escape and that's probably why I still play them. Definitely a casual PC gamer now.
Coincidently, I've just picked my guitar up again. I'm going for group lessons though. One on one is too expensive, but I think I need to be shown. Everyone learns differently.
I'd be interested in any you tube videos fellow learners are using.
