Some of my favourite games are:
Fairy Tale (A small 2-5 player card game by Z-Man Games - lots of little effects - fun)
Carrom (A flicking game somewhat similar to pool, but with flicking - Indian Carrom btw - the American Carrom Boards are rubbish)
Neuroshima Hex (A tile laying battle game - like a knife fight in a phone booth)
Condottiere (The original version (prior to FFG's version) is the best one imo)
Agricola (My wife an I enjoy playing this one together a lot)
Starfarers of Catan (sentimental favourite - always with Daft Punk playing in the background )
Rivals of Catan (two player card game - I like it a lot)
If you're a fan of Lord of the Rings then I think War of the Ring is the best LotR game to hit the market.
If you're a fan of science I also like Erosion, American Megafauna, High Frontier and other games by Phil Eklund - but they are more an experience game than a balanced game - and the rules can be highly obtuse.
