Best games for couples?

Aton is a 2-player abstract kind of game with an egyptian theme. There multiple paths of victory and is pretty fun and quick. You can get some good strategies going in this one. I have played it once with wife and multiple times with my 13 yr daughter (who destroyed me in our last match!)

I'll post you games from my closet that I played with my girlfriend. I added a (+) when my GF loves it and we have played multiple times.

Age Of Mythology: Not a perfect game in it self, some bug and issues, but the 2 player works well. Check out my variant

Carcassone(+): Plays well at 2p, we also play on Xbox.

Catan(+): My girlfriend love catan, I made an awesome 2 player variant. go check it out.

Cleopatra(+): My GF love egyptian stuff. We managed to play this one at 2 player by using a variant for making corruption giving you negative points in a trigular increment.

Dungeon Quest: Plays well at 2P, but my GF did not really like it.

Guillotine(+): This one is nice and plays pretty well.

King's Blood: Quick game that is OK at 2, but could become pretty boring with multiple play.

Leonardo Da Vinci: I tried with with my GF, it's not optimal for 2P without making a few tweaks. Using my variant could help. There are 2p variant suggestions on BGG.

Lord of the Rings confrontation: A good 2 player game (expecially with my dice variant). My GF hate it due to some conflicting rules.

Louis XIV(+): Play pretty well at 2. We use 2 AI proposed in the rules that adds influence on the board.

Mammamia(+): Plays pretty well at 2.

Puerto Rico(+): Plays very well with a 2 player variant. There are many variants out there, I could tell you what I use.

Rune Age: Awesome deck building at 2 player. My GF did not hate the game, but we only played it once.

San Juan: Plays very well at 2 player. my GF found it OK.

That's Life: Playable at 2 players, but my GF found it pretty dull.

To court the king: Also playable at 2 player. It was an OK experience with my GF.

Viktory 2: I tink I tried this with my GF, but not beign a wargame fan, I don't think she liked it.

Duel Masters/Kaijudo: Very interesting 2 player CCG, but was a very confusing experience for my GF. Apparently tapping mana is not intuitive.

Arkham Horror: Played once with my GF. Not a bad expericence, still I am not sure if the game balance is the same with 2 players. I also designed a variant a long time ago to make the game similar what ever the nb of players.

Good 2 player games that I have not yet played with my girlfriend for various reasons:

Wiz War: Seems to work great at 2 players.

Eclipse: Watch my 2 player variant setup, many people said the experience was good.

Starcraft: Very convoluted game that my GF hate, but play wells at 2.

Heroscape: Plays well at 2, but I don't think my GF has any interest in it.

Battlemaster: Good 2P game, takes a huge amount of space and might not be attractive to my GF.

Hope it helps. All the variants I designed can be found here:

Enjoy and have fun!

Onirim, Chess, Summoner Wars, Wiz War and Proteus are all great.
