Product PlacementFallout: Brotherhood of Steel features a product placement for the real life Bawls Guarana energy drink. This may be jarring to fans of the Fallout series, who are used to having Nuka-Cola as the post-apocalyptic drink of choice.
ReceptionFan response to this game was so overwhelmingly negative that Interplay actually shut down the official Brotherhood of Steel message board. Furthermore, the game's section on the NMA forums (one of the biggest Fallout forum) is called: "Fallout: Piece of Shit (PS2, XBOX, My Lower Intestine)".
Various reasons for the negative reception can be found in this writeup.
