Twilight Imperium, I play it every couple of months because it's very big, and polarity which I play more than once per week.

i don't know many board games, but am totally happy if someone can be seduced to a round of scrabble.

I play scrabble (mainly Words w/ Friends now), and Pursue the Pennant.

Pursue the Pennant is a baseball board game that I played with friends when I grew up in NY. Every visit up to NY, me and my friend set aside an entire day to nerd out.

I love to play chess. I play almost everyday on the internet.

Monopoly is still good but I haven't played it in over 5 years. I'm not much for board games, cards, games in general or on an app or a computer. I'm usually doing something else.
Every now and then I find somebody smiling and jabbing their thumbs at their phone in an excited way and I ask them what they are doing. "I'm playing a game" they say. Imagine that in a sci fi movie.

Solitaire when I am bored. Or, are you limiting the games to old style (e.g., Monopoly) board games? I'd choose Civilization, except it was not played on a real board. As a teenager, I played chess.

It's been ages since I played. Monopoly, Las Vegas were two favorites.

Splendor. Dominion. Or if we've got all day for a single game, the old classic Rail Baron.

We do many, Dune seems the mosr popular.

Does D&D count? Then there's all those chit and hex games by Avalon Hill. Zombicide is fun. But all in all, the most normie game I appreciate is Euchre.

I play scrabble a few times a month and have recently added monopoly to the arsenal

masterpiece .... rarely

I probably enjoy chess and monopoly have not played for years
