Just Cause has the graphics, sound and gameplay...but still it's not 100% satisfiying...
The first thing that strucked me was how good the game looked.
The passing clouds, the ocean and not to mention the island. And one thing that i really like is that the game runs smoothly at the most of computers...without you having to put your graphics to the lowest
There's a main story which involves a lot of action. The missions aren't that exciting...but don't worry you'll not see to many of them, since there are only 21 main story missions to complete...and then you're done. But there are also some side missions, but all of them are basically the same, capturing bases, taking over villages etc.
One thing that probably bothered some players, actually amused me. The unrealistic elements, you're able to drive a car and then jump up on the roof...and in some mysterious way, you're still able to steer the vehicle.
The character (รก la Antonio Banderas) is probably the strongest man in the world...since he's able to hold himself onto a flying airplane wing...with one hand.
Just Cause is by no doubts a good game. But you'll get tired of it pretty fast, since it's so short and there's really not much to do on the island.
P.S they're working on a sequel. My tip is to look out for that one...
