I would also point towards War Room, although that one is a very pricey game.  I've only played it with a friend who owns it, but it is like the classic Axis and Allies all grown up!

I second this

I've seen this game on the shelves of a few of the gaming stores in my area. I heard it's similar to Terraforming Mars. I've been debating on whether or not to pick a copy up.

Pandemic: Legacy is SO much fun, you change the board and add to the rules and rip up game pieces and shit as you go, every round you're opening up this little advent calendar of new mechanics and plot twists etc

This War of Mine is a surprisingly cool board game, much harder than the video game it's based on. comes with a book (or an app) full of plot snippets that you're prompted to read from at certain points, so it's like a choose your own adventure story except most of the endings are bad heheh

currently enjoying terraforming mars.

The Arkham Horror card game is by far my favorite board game. It's co-op vs the Evils of the Cthulu universe, and has near endless replay ability through its multiple stories, and even some great fan made campaigns

Twilight Struggle!

If you have a group of friends, then I think "BANG!" is a lot of fun.
The Quacks of Quedlinburg is well worth a look.

Definitely Betrayal at House on the Hill, and Wingspan

Definitely ludo and carrom. The board games that I grew up with. They're super famous in my country.  Though I never get to share my love for them online as almost nobody has ever even heard of them. Joy :")

This documentary got me into it.

From there it was all over.  I’ve bought my own board and play with my boys.  I take it on all of our family vacations and my father in law and I play.  Great game.

On my phone (iPhone) I’ve been playing Badukpop (Go)

If anyone plays hit me up I would love to make friends to play against and learn from.

Spirit island.  Over 100 plays and I'll happily play 100 more.

I got this board game years ago and I liked it a lot. Elixir of Life. Where you are a wizard and are playing against other wizard moving around the board and have to avoid being mugged by thugs and have to go around to the shops to buy ingrediants to make a potion. Where there are plenty of differnt potions you have to brew all threee elixirs of life to win the game.

Not sure if it's been mentioned, but I've played Seven Wonders quite a few times with some board game nerd friends I have. It's pretty chill and approachable to people that aren't entirely down the board game rabbit hole.

Me and friends enjoy co-op vs game/deck games or light competitive 

7 wonders 
Dracula
Betrayal at house at the hill
Lords of Waterdeep
Ticket to Ride
Eldritch Horror
Arkham Horror

D&D boardgame series are decent but we most collect 'em for the minis. Cheap way to get nice minis

Monopoly, Catan, and Starfarers!!

Twilight Imperium: 4th Edition
Through the Ages
Terraforming Mars

Oh yes, I tried Pandemic Legacy 1, and I got the second tier of the scoring system

chess.

just saying.
it may be a classic but its still good.

I enjoy most of the classic board games..... Monopoly, Risk, Sorry, etc.

Then there are the games with added flair :)
Dead of Winter <--- highly recommend this newish (2014) game if you haven't tried it yet
Doomlings
Mysterium
Forbidden Island

I'm definitely forgetting some favs at the moment - will probably come back to edit :)
