The game is what you make of it.
All the other Fallout games are single player, and should be played as such.
I personally am getting a great deal of satisfaction from working with other people to accomplish a goal.
It's not hard to find decent people in this game, unless of course you present yourself as an 8-12 year old, whining about the game and the people who play it.
The decent players will avoid you.
If and when you see me, and you are a level 3 blue suit, don't act like an ass. I'll simply walk away.
If instead you are decent, ask questions, and don't act like an idiot I will answer those questions. And probably give you 10 brahmin hides. Or a weapon and ammo, or armor, or caps, or a ride somewhere.
Based upon my personal experience, what you get out of the game depends entirely on how you approach the game. If you want a different experience, try approaching it differently.
Instead, if you want to continue to bellyache, feel free to ask for your money back.
