I love Mass Effect, Dragon Age and Skyrim. I have The Witcher 2 and 3, and I'm honestly afraid to start them because I KNOW I'll disappear for weeks at a time to play them.
I'm also in the middle of replaying South Park: The Stick of Truth. This is prep for the upcoming South Park: The Fractured But Whole (say it out loud).
The biggest thing dragging me back into games is I like getting every last achievement. It's almost an OCD thing for me. But RPGs and action RPGs are huge for me.
When I'm not doing those, I seem to have developed a thing for racing games. I've spent a lot of time mindlessly venting with Forza. I do so in single player because I am take no prisoner when I'm driving. lol
