Did you finished Fallout 1 and Fallout 2 without deaths?
I always play RPG game like diable as a Hardcore Character. No matter how long it took I tried to finish the game without deaths of my chosen hero. For Diablo 2 I only manage to finished 2 Hell Stages. So I tried it in fallout if I can do a hardcore character. After many tries and many hours of experimentation with the stats and perks I manage to finish Fallout 1 without deaths and also my companions are also alive. Same as fallout 2.
Maybe next week I will try fallout 3
It's more fun playing when something is at stake. If my character dies in an RPG game I automatically start a new game.
