The successful balance between exciting innovation and comfortable familiarity is a delicate one. It's true that large doses of creativity can sometimes lead an otherwise solid project wildly awry, but on the other hand, there's little value in rehashing ideas and not going far enough. In the case of Just Cause, the developers have innovated with one shining addition, but otherwise let the scales weigh heavily with well-trodden material.
