Favorite Free/Open Source Game

[Aurelian]

For those that like ancient warfare (which should include everybody here), I recommend a free computer game called "Hoplites".

To pull the description from the 'web-grognards' site:

Hoplites is "a free computer card game based on SPQR. In Hoplites the player controls an army and fights against the computer. Each player (human and AI) use a deck of cards that represent the units (infantry, cavalry …) and special commands (flank, rally): from these decks the cards are drawn and played on a "field" represented as three zones: the Centre and two wings (left and right). On the fields the units move, missile fire and shock with the enemy."

You can also play against other people, both in hot-seat mode, and via e-mail.

I've really enjoyed this game. The designer and fans created a whole collection of army decks, and the game comes with a deck design program. Romans, Greeks, Macedonians, Celts, Germans, Britons, Chinese, ancient Egyptians, Hittites, Indians, Persians, Parthians, and more are all represented.

For those who like samurai warfare, there is a "Samurai" add-on to the basic game that introduces clan-based warfare and new game elements.

For those who like fantasy, a "Conan" module was also added that lets you play as any of the city-states or demonic hordes of Hyboria.

Hey, try it out, it's free.
