I used to play competitive DOOM (was in the ZDaemon top 10 almost a decade ago), and while the BFG9000 was certainly the most powerful weapon in the game, it was also the most seriously misunderstood. New players would always attempt to spam the BFG in a crowded room, then duck behind a corner or run away. Due to the mechanics of the BFG, this is the opposite of the correct strategy. A short time after a BFG impact with any surface or object, the game basically performs a cluster of hitscans radiating from the player in the direction the shot was fired. Thus the most effective BFG strategy is to stand to the side of an entrance to a crowded room, shoot the BFG at a wall, and strafe toward the entrance until as many enemies as possible come into view. Get the timing right, and you turn the room into an uninhabitable no-man's land until your six shots run out (ten if you grab the ammo backpack). I miss those days :)
