Hey guys, I am getting GTA 4 Tuesday and i really have a few questions to ask?
What are the Features in the Game?
Can you do whatever you want?
Can you jack a Plane?
Any other Features that make it cool?

Its similar to other GTA games. Unfortunately you can't steal planes in this one. Dunno whats up with that though, you could steal planes in SA.

Damn, I know I could steal Helis, is that true?

yes u can steal helicopters in this
you have to wait them to land

Can you be able to rob places?

I think you can rob banks?

Something I heard a while back. Maybe not though.
