Picked up Rocksmith 2014 remastered for $3.00 in the last steam winter sale and it needs the converter cable from a 6.5mm Electric Guitar plug to USB in order to function. So I snagged one of those.
Its honestly awesome, and Rocksmith is a really incredible teaching tool. Basically guitar hero with an actual guitar and lessons. I'm not going to be the greatest guitarist in the world, but simply being able to listen to a song and understand/visualize the techniques the guitarist is using to create the music is a gift unto itself.
It can seem like magic without the knowledge, and then its actually so elegantly simple with even 101 introductory level knowledge...
