But that is just a game setting, there are no real restricstions on that kind of a code.

The time is controlled by the timer, and as the timer can be changed to pretty much anything then it is easy to change how long the game will last.

I am 'guessing' that changing the number of players allowed into a game takes more than just changing the number of players it 'says' are allowed.

I am not saying I know, I am just taking a guess.
