Jagged Alliance 2
Jagged Alliance 2 is old, but a classic and excellent game. Recently I got it working on my MacBook by compiling the Straciatella project.
I made this page to publish helpful information on the game, and keep it alive. I am still enjoying the game, 10 years after I first played it.
