Good for the people who found ways to make money off of long-established games that can mostly be played with stuff laying around the house. Here are a few games that you can try, probably without having to lay out cash.
Liar’s Dice: you need 5 dice per player and a Dixie cup per player. OK, if you don’t have 20 or so dice laying around your house, then this game is probably worth its asking price. But then how serious a gamer are you?

Dictionary Game or Fictionary, Sure, you can find it at game stores under the name Balderdash. The Balderdash producers added a board and other categories to give you more bang for your buck. But the basic game remains unchanged from these basic rules. You just need a good dictionary, some paper and pencils.
