nicking the jetpack is PROPERLY fun

as for the liberty city mission, you fly out to sea and then youre transported to liberty city. you have to run thru a restaurant or something and kill some people. then you go back to san andreas. it's only a small bit of liberty city, 2 or 3 buildings, but its a very nice addition.

one mission i never did do was the casino robbery one, i'd like to go back and do that some day, but it means completing the game all over again
