Just beat this game yesterday, I wanted to wait a day to write the review. Lets start with what I dislike:
I think that game developers, in order to make sure you have plenty of hours of gameplay to give the sense that the game worth every cents, add several repetitive side quests or missions that at the end is nonsense but when you finish the game you say wow, this is a 50 hours game. However, 8 hours are main story and learning curve; and the remaining 42 hours are repetitive side quests missions. Well, Just cause 3 is this kind of game. I mean, it is OK to have plenty of side quests but not this proportion of 85% of overall time invested in the game finding artifacts and destroying camps, towns...
The good side: Very addictive.
This game has something, that even though, it is very repetitive, you never get bored playing it. The main characters are great. I mean, it could be greater if instead of repetitive quests, the developers would have addressed more time by developing the characters and more cutscenes.
The graphics are good. The destructions are very well developed.
The rest of the game is OK. The Story is good enough. But it should have been more oriented to develop it and make feel players more connected to characters.
