Western In My Pocket is a free print and play tile game. From the BGG description:
Players lay tiles beginning at the Sheriff’s Office, and must find dynamite at the Survey Camp and get to the mine and blow it up before noon. While you’re doing this, there are bandits around that will try and stop you. Western in my Pocket features a modular board, so no 2 games are ever the same.
Cthulhu: The Great Old One is a simple, free print-and-play card game.
Warbucks is currently up on a Kickstarter, but the print-and-play version is free. The author describes it as a deckbuilding game like Dominion, but with territory control:
The deckbuilding component is more action-focused than engine-focused, but I’m not ashamed to say that I borrowed a fair bit from Dominion, and learned a lot about card interaction, pricing, and design from reading dominionstrategy.com and playing lots of Dominion when Isotropic was still running Dominion games.
The base of the game is a territory control game, but without the dice rolling that you have in Risk. If 4 armies attack 3, 1 survives. That’s a fun half of a game (surprisingly), but what makes it interesting and provides a random element are the cards. Basic troops can move and attack, and that’s it. More interesting behaviors like jumping over enemy lines, moving farther, and hitting harder as well as responses that you can play on defense are in the cards.
There’s also a strong diplomacy/negotiation component to the game — it helps to convince people that you’re not a threat so they go after the other players, and there is bribery built right into the game to provide one more method of inducing cooperation from your (temporary) allies.
Your army holds territory, territory produces money (WarBucks), and you spend money on more troops and tech for your troops in the form of cards.
Zeppelin Derby is a free print and play game that uses just 17 cards. From the game description:
It’s race day! Aircrews to your Zeppelins! In this fast-playing racing game for two intrepid Zeppelin pilots, the players race their airships by rolling dice and playing cards — including a few dirty tricks! Who has the moxie to cross the finish line first?
Witch Hunt is a print-and-play card game with just 18 cards. It’s a “traitor” style game with a twist.
