The mission for Packie later on is just like the heist in the film Heat. Tough as nails, it took me a few attempts and my heart was pounding like mad as I tried to outrun the coppers. Most fun in a game I've had for a while.
Being the huge Heat fan that I am, that may be my favorite mission in this game outright.
The mission nets you 300000k. What the hell can you spend the money on?
Nothing.
That's probably the biggest complaint about the game itself a lot of people have: There's little financial incentive in this game and there's really nothing to spend money on after a short point.
Assuming you don't cheat, you buy the weapons and ammo you need ever so often and buy a couple of plot line mandatory clothes changes and...that's pretty much it.
I sorely miss buying properties and other assets like that which made it feel like you were making the world more "yours" and working towards something.
