I really like what tumbajumba did in fallout 3 with the scavenger armor mod.
He openden a shop
You have to buy them there ,they are not too expensive and not too cheap.
I dont really like 'the easy way' ,it destroys the whole game.
You start and find one of the best guns in game just infront of you ,nothing is a problem now ,you can kill everything in some seconds.
But there are some really good mods out there wich do this.
There is a box with cool stuff in it.
I install this mods later so the whole feeling do not get destoyed
