At my place the most played have been Settlers of Catan and Ticket to Ride. Easy to learn and lots of fun. Then there is Cards Against Humanity. Another popular one is Ascension. Also easy to learn and a lot of fun. They have a lot of different sets since they seem to update and come out with new versions every year. If you don't mind putting up a bit of money Cyclades is great.
