While board games had started to die out a decade or so ago, they're making a comeback with a vengeance in recent years, primarily due to the emergence of the so-called "eurogames" like Settlers of Catan (one of my personal favorites) or Carcassonne. My wife and I are avid gamers, both in video games and board games, and we have gathered a fairly impressive collection of these newer board games (also defined here to include card games that don't utilize the traditional 52-card deck). The ones I can think of offhand include:
Settlers of Catan (and it's expansions)
Carcassonne
Talisman (and an expansion)
Chrononauts (and it's expansions)
Guillotine
Stronghold
DungeonQuest
Arkham Horror (and one of it's expansions)
Betrayal at House on the Hill
Fluxx (with the Jewish expansion!)
Munchkin (Munchkin Booty, the pirate version, as well as it's expansion 'Jump the Shark')
Cosmic Encounters
Dominion (and a couple of the expansions)
Shadows over Camelot
Kingsburg
Thunderstone (and most of the expansions)
Lord of the Fries
Battle Cattle
Car Wars
Elixir
Ticket to Ride
Citadels
And all of these are in addition to several of the more classic Parker Brothers of Milton Bradley games like Monopoly (of which I own several versions), Life, Scrabble (of which my wife owns several versions), and Risk.
I really do encourage anyone and everyone to find a local gaming shop that hosts board game nights, which most seem to do. They typically either have a bunch of people who bring games in with them to play with people, or the shop provides store copies for people to try out (in the hopes that they'll then buy a copy for home). These games are mostly excellent, have great replay values, and are so much better from a monetary standpoint for long-term entertainment than going out to do stuff. My wife and I get together with friends at least once every few weeks and spend the better portion of a day playing various games, and it's so much fun.
