I have neglected this thread for too long.
I love me some board games. I have a nice massive closet full of them. I have infected the other local YGG people into expanding their own collections and if there is a popular game I don't own, chances are the reason is that everyone else owns it instead (this is the case of me and Smallworlds, so many other people own it and expansion it is redundant for me to get it). In fact, I've been meaning to start recording when I introduce a new game, because I think there could be a bit of demand for that, or not maybe, but you never know.
Some of our favorites are Smallworlds, Red Dragon Inn (I'm the current master collector of this with all versions and expansions but Jack is catching up), Munchkin, and Cards Against Humanity which aligns far too well with our level of maturity and potty humor.
Also worth mentioning is Ticket to Ride, which is the game my family goes crazy competitive over. Simple but fun, and we've picked up an expansion board to spice things up. My mom has the highest tally of wins I believe.
Some of personal favorites and highlights in my collection are Pandemic (with the, required in my opinion, On the Brink expansion), and classics like Carcassone and Puerto Rico, which unfortunately are usually to complex for most other people to remember the rules and require some explanation, so I don't see much play. My favourite trivia game is Wits and Wagers, and Spot It is a very fun and quick reflex image-matching game that is great for almost all ages.
However, currently I'm in love with Lords of Waterdeep. Just ask @Drkladi
how seriously excited and in love I am with this game. It is beautiful, elegant. The fun and complexity of a euro game with mechanics that take less than five minutes to teach. The night I showed it to them and Jack and Mandy we instantly played it twice in a row, so much fun was had. And now an expansion is coming out. But this game is one of the best purchases I've made, an easy to teach game with robust mechanics, it is a fast favourite and will likely continue to be. I'm holding myself back because there is so much I could gush about this game.
