Ok so there aren't really any big differences but incase someone is interested here it is.

Version 1: This is the version you'll probably find 99% of the time on the internet and in early copies, it's the most common of them all and it has the normal Nightride crash and "You're Winner!" win message.

Version 2: This is the version which is usually found on later released physical copies, not a lot is known about this version, i only know of it's existence from AVGN's Big Rigs episode since he says that he has another version. It's basically the same as Version 1, the only difference known right now is that "You're Winner!" is changed to "You Win!"

Version 3: This is the patched version. This version fixes the Nightride crash so that the map is playable and makes your opponent move (although if he reaches the finishing line before you, you will still win). The patch doesn't include the win message fix so if you patch Version 1 to Version 3 it will say "You're Winner!" and if you patch Version 2 to Version 3 it will say "You Win!"

Well those are really the only differences i know of, this isn't really helpful i'm just leaving it here if someone wants to know
