My wife and I have played Terraforming Mars a ton. Maybe 40 times..... Because it's so long, I'd have a hard time thinking of the number of hours.... after that we've played Splendor a large amount but those are usually quick, like 15 - 20 min, especially on trips and vacations.... so maybe 50 plays of that. Wingspan at least 15 times. so it's knocking on the door. Oh wait, Ticket to ride if you don't count separate maps would definitely be 40 or so plays, including with non-gamers. There are other games I like more, but I was wondering which games actually get played the most by you? I'll start.
2. Terraforming Mars
3. Ticket to Ride (various maps)
