So, I decided I want to try something. I stole a boat in GTA IV and I taped the controller and the boat is still going. I'm not even sure how far out I am, but well see when I wake up. Updates to follow in the morning.

Maybe, I'll come across England, or maybe I'll just go forever.

Update! It's been about 5 and half hours later. My batteries were dead so I just switched them out. Niko is still going strong on his journey.

Final Update: After 4 days of relentless drifting in the waters of Liberty City, the end was no where in sight. Niko had gone off the map and was in water that never ended. So if there is land outside of Liberty City, it will be more than 4 days away.
