Amazing Game ;)

Quests

 * Following in His Footsteps: Passing a speech check will give you immediate information about your father.
 * Galaxy News Radio: Failing, or not taking the aforementioned speech check starts this side quest. If you pass that speech check, you can immediately reinstate conversation to have both quests running at the same time. You can also come back later, or see him for the very first time after having made progress otherwise in the main quest to find your father, and if you bring your support to his "good fight", Three Dog will also give you this quest.
 * The Search Continues: Killing Three Dog before he tells you to go to Rivet City at the end of the quest "Galaxy News Radio" starts this quest.

Effects of player's actions

 * Three Dog will comment on various actions of the player through his radio broadcasts.
 * On Galaxy News Radio, Three Dog will constantly refer to the Lone Wanderer by his/her current Karma title.

 * Erik Dellums helped develop the character, including his signature howls.

Bugs

 * Occasionally, Three Dog will mention events that occur after the ending of the game. He will only do so if the player had downloaded the Broken Steel downloadable content and has not played through the part in the game before it.
 * Sometimes after starting a new game, Three Dog can be heard stating things that haven't come to pass yet. This has been known to last until you catch up with the event that he's referring to.
 * Sometimes Three dog will start saying a comment and then quickly switch comments about the player over and over again. This can prevent you from listening to music for the rest of the game.
 * Occasionally Three dog will repeat the "News" section of broadcast 2-3 times over until he will continue playing songs again.
