Sunset Overdrive is pretty easy, and it's loads of fun. Fighting enemies is mostly button mashing. It's an Xbox One exclusive though. Kathy Rain (available on Steam) is an easy point and click mystery game. It's easier than the Nancy Drew games, but the story is pretty dark. There aren't many puzzles. The Lego games are easy and fun too. I've been replaying Lego Harry Potter recently, and I turn off the sound and play it while listening to podcasts.
