Mexican Motor Mafia
Mexican Motor Mafia is an indie game by J. M. Loehrlein and Michael Geiger in the style of Grand Theft Auto where the player has to drive cars and shoot different weapons. It's also very similar to the old Autoduel game with skills you can upgrade, and a large explorable world. It also includes elements of Sid Meier's Pirates!, namely trading and defeating named bandits.
The game is released as shareware, where only the 2 first episodes are playable without purchasing the game.
