just tried the demo on xbox 360 and I'm not that impressed; the only thing going for it is the graphics and the size of the world and the graphics aren't amazing, they're good but some things look a bit poorly textured, the environments are beautiful though.
Without the graphics and the size of the world this game is extremely poor in my opinion, the cars drive all the same and it's very arcadey, the just slide along slowly getting faster. The character animations are quite bad and the main character runs like he's just been kicked in the nads.
The gunslinging is okay but i swear my cat could play this game and not die in a gun fight, the guns are varied but there seems to be no incentive to use different guns; his handguns are actually better than a machine gun.
Don't even get me started on his seemingly supernatural acrobatic abilities, he can jump around like spiderman, even through helicopter blades, he can jump from one car to another nomatter the speed of the cars involved, the second you remove your foot from one car at 100mph the car in front or behind you will be 20 feet in front of you but in this game when you jump from one car time apparently stops still for you to land on the opposite car.
Also, one thing I'm confused about is.... how the hell can you drive a car when you're standing on the roof?! Ahhhhhhhhhh.
Also, the parachute thing; apparently if you pull your parachute 10 feet in the air it will still save you from splatting!
Overall, unless they fix the unrealism that is Just Cause I'm going to buy a copy so I can fling it under our car.
