As a true boardgame geek/junkie
I am always on the look to get my fix. Here are a few of my favorites.
Diplomacy - Classic game of pre-WWI Conflict. Most of the game is negotiations between the various world powers, with generalized military engagement
Riccochet Robot - Great party game 1-100 players. With 96 permutations of board and nearly infinite movement possiblities it is never the same game twice.
Zombies!!! - Romero Zombie movies brought to the table. The basic game is adequate, but the ability to stage your own plot/victory conditions makes for a lot fun.
Guillotine - cardgame of beheading in the french revolution. Cheesy french accents a must
Scabble - no explanation necessary
Chrononauts - Card game of time travel and alternative history
U.S. Patent #1 - Race to get your time machine registered as the first US Patent
Fluxx - card game of ever changing rules
Junta - Be El Presidente for life of a banana republic
Ogre - Man vs. giant cybernetic tanks
Little Green Things from Outer Space - Just like it sounds.
Strat-o-matic Baseball - Currently preparing to recreate the 1975 season.
Twixt - classic 2 player strategy game
War of 1812 - 2 player fog of war strategy game
Rise and Fall of the 3rd Reich - AH WWII classic. For accuracy leaves Axis and Allies in the dust
Wake Island - 2 player WWII hex and counter game.
