Now I do have an additional proposal:
Bohnanza by Uwe Rosenberg
While cruising at sea, Bohnanza places you firmly back ashore. - It is a card game
about planting, trading and selling 11 different kinds of BEANS. You try to collect and plant various types of beans to sell for gold. There are always new beans to plant and each player has limited growing space. To avoid planting unwanted beans, players need to trade
The gameplay involves very little luck, it is a serious strategy and negotiation game
I promise that your IQ and your honed business skills might turn out to be outmatched
by the social skills of one of your "unexperienced" kid players - watch out. No adult experience advantages, no lucky "Jail" or "Sorry" cards but also never no "turning the board over" frustration.
Find yourself in the midst of a bean trading war at your dinner table, maybe with embargoes against "the bossman" while other players get away with creating a bean cartel.
...and YES the business-tycoon couple that would never touch a boardgame turn out to be neglecting our "Brunello di Montalcino" in their fight for supremacy.
- SERIOUS FUN - (like Catan)
P.S.: Don't know what you mean with "A" addition for CATAN but SEAFARER
of course comes to mind 1st.
P.P.S.: Now for those in the thread that are still on "Scrabble" and "Monopoly"
(or mAh dependend)
here's what Erik Wecks of WIRED
had to say about "Settlers of Catan".
"Somewhere along the way, someone has probably introduced you to the board game version of cocaine, The Settlers of Catan. If the sales figures and stats are to be believed, you got addicted. Without a doubt, Settlers is a modern classic, the Monopoly of today. The game hits the family game sweet spot in almost every way. You can play it over and over again without feeling bored, and it appeals to a wide audience, from children at age 9 to grandparents aged 69."
