Georgia Boardgames Association

One son loves this, but I’m still striving to understand why everyone appears to love this game so much.  I have been told that historically it was the first of its kind.  I’m just not getting the attraction, but it is somewhat entertaining and easy for younger children, even though, it is not a child’s game.  I have been told that expansions are more fun.  I’m hoping someone can tell me the attraction.  Are other tile laying board games better?
