http://youtu.be/2_9OYdJB6Uo Niko McFly enters the world of Liberty City with this phenomenal mod. It's difficult to find the original mod, as there are several different variations. However this is just one of the hundreds of Back to the Future mod videos I stumbled across that caught my attention. The idea seems fairly simple, but the execution and development are beyond complex. Many modders have attempted to create a successful version of this mod, but few have been truly successful. While there is a limit on the actual time that can be traveled, the idea of saving traveling through Liberty City at different times and days with the flip of a switch is quite fascinating. The DeLorean is perfectly designed and rendered, the animations are flawless, and the sound effects are spot-on and true to the movies. In short, this GTA IV mod is as genuine as it is entertaining.
