Samurai Blades is one of a series of board games published in 1984 by Standard Games and by now long out of print. The game was essentially a skirmish game played on a hex board, with cardboard miniatures. Each character in the game was represented by several pieces, each depicting a different level of damage and injury. The web page at the link has lots of resources for the game, including the rules and gifs, tiffs, and jpgs of the pieces and boards. This is really useful if you have the game but have lost one of those aforementioned damage markers.
Panzer Clash is a free print-and-play card game with a World War II theme for 2-4 players. From the BGG decription:
Pick a side, either Axis or Allies, and build a deck of 40 cards out of a pool of 100 different cards in order to defeat your enemey.
The deck or Supply contains Factories, Units, Events and Terrain Modifiers. Factories are needed to build Units and Terrain Modifiers as well as to power Events. Units and Events, which usually belong to one or more of the four factions (Germans, Japanese, Americans and Soviets) are used to attack and deal damage to the opponent, have certain beneficial effects on the game or are used to weaken the opponent. For each point of damage a Player receives through Units and Events, he or she puts one card from his or her Supply (deck) onto his or her Junkyard (discard-pile). Is a player unable to draw a card from the Supply, he or she loses immediately.
Witch Trial is one of Cheapass games most popular products. You can get a print-and-play version of this game at the link.
In Witch Trial, you play an attorney at a prestigious law firm. You will act as a prosecutor or defender in several cases involving unmarried women, free thinkers, vegetarians, the homeless, and other undesirable types. While witchcraft per se isn’t really a crime, it’s customary to bring suspects into court on related offenses, such as card playing, smoking, and tampering with the post.
This game requires lawyer-like reflexes, a little bit of luck, and the willingness to bargain when you know you can’t win.
