While it may have looked like you didn’t know where you were going or that you had ADD whenever you input the myriad codes in the GTA series, no other video game in recent memory gave you more for your cheating heart than this series. Infinite weapons were only the beginning, hombre. You could do so much more if you just futzed around with the buttons and controls.
Foggy weather, Get a tank, and a whole slew of other codes were all fair game. With an open, sandbox game like this, entering codes and fooling with them was like a totally different game entirely. It made the game that much better, and it was already a pretty awesome game to begin with.
