Oof, lots of board games. My family has gotten into them pretty heavily.
Ticket to Ride. We play this a lot, and have a bunch of the expansions. It's pretty much our go to when family comes. (And I WILL avenge myself on my own mother for cutting me off from my longest route last game.)
Betrayel at the House on Haunted Hill. Or however you call it. We just say "Haunted House". Brilliant game, lots of fun. occasional stinkers though if the end game ends up hinging on bad rolls rather then anything exciting.
The Dresden Files Board Game. A personal favorite, but not one I can get many playing with me. Luckily it has a solo version, and a video version on steam.
Cribbage. It counts as a board game right?
Spyfall. Another personal favorite. One person in the group is a spy, and everyone else gets a location card. You go around the circle and ask each other questions, while the Spy has to figure out what the location is and everyone else has to figure out who the spy is. Fabulous with a large group of friends and a few drinks. We played it for ages at my buddies bachelor party.
Pandemic a few times.
Dead Winter once or twice.
BlackStone Fortress maybe 6 or 7 times, I forget how many for sure.
A bunch others mostly one off.
