I don't think we ever play any games by the printed rules ever. Mostly we combine multiple games and usually add drinking and betting rules somewhere.
My personal favourite is drinking Cluedo where it is normal cluedo but everytime you roll a 1 or get called into a room you have to take a drink. This sounds like a normal drinking game but is subtly effective because if the other players start to think you are working it out they ca just all call you into the room and make you take a whole lot of booze very quickly so you quickly forget your theory.
In the non-drinking side my favourite would probably be the existential game of life where we redecorated a game of life board with new clues, new pieces and new pathaways- the college pathaway is a giant looping vortex where it is nearly impossible to escape the constructs of others and to win the game you have to destroy your own playing pieces bit by bit. I should point out that this was invented because the original game of life is broken as all fuck.
The best bit, though, is we left some of the original cards in there so in between cards that mire you between your biological urge to have children and your own unfufilled dreams are cards like You have become president of the united states. Good times.

Haiku scrabble is a good one too- basically it's scrabble but we have syllable numbers (for example 5, 7, 5) and you cannot go over the syllables remaining for each line- for example player 1 plays a two syllable word, player 2 can only play a 1,2 or 3 syllable word- say he plays a 2, player 3 can only play a 1 syllable word, then we are on a new line so the next player can do anything up to 7.
