just cause 2 would be good if it was multiplayer or multi-coop at least. I easily got bored of parachuting through the jungle and blowing up the same base in a different location. Now the only time I play it is to show a friend how ridiculous it is for like 5 mins. Quickly order up a prototype spylane of sorts, kamikaze it into an explosive silo as you quickly grapple yourself to someones testicle and magnetize to their general direction.
its original in that the graphics are better, the sandbox is bigger and your character can basically fly, but its practicality is explained through the use of infinite parachutes and batman's utility belt.
its great...if you lack an internet connection.
I wonder if gta IV has a grappling hook mod. Then this game would be exactly the same, but set in a massive chain of jungle islands.
