PipboyFallout SeriesNot an actual character, but an illustration that appears in the game and in the manual whenever a game concept is explained. You can't play any of the Fallout games without becoming a fan of Pipboy!
Illidan StormrageWarcraft SeriesHe betrayed the good guys, he betrayed the bad guys, but mostly he's just addicted to magic. He's the bad guy you can't help but feel sorry for, and within the game, he seems to have become the hero/leader to just about every group of outcasts that don't quite fit in with one side or the other (Alliance, Horde, Scourge, etc.). At the rate he's gaining followers, he could become a faction unto himself in some future Warcraft game, but only if his former matsers don't kill him first.
HaroldFallout 2(no image)
Deformed by radiation, carcinogens and engineered viruses into a long-lived ghoul, Harold is the ultimate repository of bad jokes and pointless stories.
Jolee BindoKnights of the Old RepublicSort of like Harold, only he's a jedi, tells fewer bad jokes, tells more stories and the stories he tells are even more pointless. Maybe I just find cranky old men amusing.
Anyway, share your favorites. Please avoid mentioning console games that have been ported to PC.
