Main exports:
USA to Spain: Petroleum
Spain to USA: Refined Petroleum
Now, I'm sure this is bad business for both parts, but it's a helluva lot worse practically for USA to be without refined petroleum than it is for Spain not to have petroleum to refine.

I had to mention both, because I like them for different reasons.
Initially I didn't even like Vice City, because it was just an epigon of GTA3 with more lens flare, but the story and not least the music won me over. I know it's a blatant mockery of Scarface, but that's what makes it so great and funny.
San Andreas is probably the masterpiece of them all. Maybe it got a little too serious in comparison to previous games, but it managed to portrait a great feeling of freedom and doing whatever in-between the main missions.
GTA V is more like: Follow the arrow through this generic oversized map.
