How long is the main campaign for GTA IV? (possible spoilers?)

[stonewall99]

I'm finally on to the third island, and just unlocked the assassination missions.. I think I've been playing the game for about 22-23 hours.. How long is the main mission campaign? I'm trying to see if I can complete it in less than 30..

92-94 story missions

60% is when you will be done with the story. If you didnt fuck around and stuck to the missions you should hit it before 30 hours.

Ah.. Excellent.. Thanks.. I think I'm around 52% complete..
