Is there a game like just cause 2

Games similar to Just Cause 2 are the previous Just Cause series game, Grand Theft Auto and perhaps Saints Row. I find that JC2 is the most expansive and varied game in its environments and experiences. The last two games in that list also have more violence and have unethical themes, that may be something to keep in mind. You can also check out other games under the categories of Open World or Sandbox games. You may also want to search for Third-Person games, they would be more similar to Just Cause 2.
