The "good" board games tend to take under an hour to play, and where Monopoly lags for about 2 hours after the winner is a foregone conclusion, the "good" games come to a sudden end just as it becomes clear who will win.
By "good" game, take a look at classics like Catan, Carcassonne and Puerto Rico (which are all about the same complexity as Monopoly yet have a lot more strategy involved than luck) or less well known ones like Power Grid, and Ticket to Ride.
If you want a light little party game with lots of social interaction and bartering, take a look at Bohnaza. And if you like rolling dice, Formula De is hard to beat.
Bright out Monopoly if you want to spoil an evening.
