I talked with my friend and fellow fallout fan, Eepee, about the games. This not only impacts how people react to you, but also what companions you can get. As you know, if you steal or lie your karma decreases. The Karma system is also a good edition to the game. Every little thing you say and do adds up in one way or another.
If you side with one group, you get shunned by another group.
Say you let someone die, that will effect how others act towards you. With Fallout you are the lone wanderer and the decisions you make effect the lives of others and therefore the wasteland. When you play a game like The Last of Us you play as a set character with their own personality. What is great about the game is that you play as yourself, making the game more immersive.
