With just one letter...

[Een]

... will you be able to guess the name of the next game?

The first clue is: C

Edit : the second clue is: very hard

Edit² : the good answer is Diam's from Lionel Borg, published by les XII singes. It's a combination card game in which you'll get rich collecting diamonds!

[Cristiano]

C has a shape of a Boomerang!

[astrero]

also as a "Luna" (moon)

[Brain]

"C" for Carcassonne, the letter C is on the back of every tile in the game
or settler of Catan
or Citadels

I guess there are a lot of games that start with a C...

[Coyotek4]

I'll take a shot: Castles of Burgundy

[Oso]

Castles of Burundy, Blue Moon, Citadels

[igorknop]

Clue.

[SonGoku]

"C" i hope Settlers of the Catan or Carcassonne .

But Carcassonne was here,then removed,so i dont know

[Volguus Zildrohar]

Looks like the black mana symbol on Mage Knight dice, so my guess is Mage Knight

[Captain Gidsen]

Conan! Of course!
