As a player of all fallout games I have a tiny gripe, I have lots of ideas for fallout games or downloadable contents.

I remember meeting the brotherhood of steel for the very first time. That totally awesome armor they had and the biggest and baddest guns in the game. Elder maxson, yeah. I remember that the brotherhood asked me to help kill the enclave.

A lot of new kids to the fallout series want to get away from the brotherhood and enclave. I personally think this is the bread and butter of the fallout series. The new ncr introductions in new Vegas revives fallout 1 in a sense. But the lack of real brotherhood presence is saddening for me. The remnants were a good addition for me.
Fallout 3 was great, it had the best of the brotherhood and enclave desires.
Now the next fallout game or games. I would like to see a little more brotherhood enclave. Not a full scale game based on them alone. But a bit more influence if you want it.
