Grand Theft Auto III (GTA3)

I really enjoyed playing "Grand Theft Auto III" (GTA3) on a personal computer (PC).


People who develop video games often create game scenarios that have seemingly inevitable outcomes, typically leading to the death of characters.

However, I like to "change fate", using the rules of the game environment in such a manner as to rescue game characters from being killed, sparing them from the sadistic wishes of the game developers.

In this article, I explore some of the possibilities with the games "Half-Life" and "Half-Life: Opposing Force".
