Another nice free online game is World Golf Tour. The golf courses are stunning. It's fun to play. You can play against friends online. They have lots of monthly tournaments too. https://www.wgt.com/
Diablo 3 (which if you havn't played it since they made some changes I recommend coming back and trying it out!), World of Warcraft, and Scarlet Blade. I play the last one for the story, I promise! XD
