Monopoly the card game trumps Monopoly the board game. (And we play it with ‘house rules’, where the instructions card acts as a “financial tsunami” and wipes out everyone’s money. Plus, it’s much faster.
“Carcasonne” is also a great game, the Wheel of Fortune version is particularly very well balanced.
Recently we also have been playing “Empire Builder”, which, like Risk, is a really long game. It also takes a while figure stuff out.
I don’t know if this counts, but the most fun I’ve ever had with friends and a board, dice, etc are the traditional pencil and paper role playing games. (Good old “Dungeons and Dragons”). Huge time investment, but the creativity and EQ involved!
