NalNalas and I are having a discussion of whether or not Just Cause 2 and Grand Theft Auto IV are similar. He thinks that they're not similar because GTA:IV takes place in Liberty City, the gameplay is different, the storylines are different, no health regeneration, and there is no grappling hook. I think they're similar because they are both open-world games, they both have non-required missions that increase your progression throughout the game, and the gameplay mechanics are nearly the same.
What do you think?
