I didn't grow up playing video games, but after years of watching my husband play for hours on end, I decided to give it a try myself. He helped me out a lot (and still does at times) with showing me the ropes, but a lot of learning comes from actually playing. Seeing how other people play can help out also.

To answer the question of how your gamer S.O. can lose track of time playing, pick up a controller and hit start.
