VTMB is one of my all time favourite games (despite its extreme buginess and bad performance) and while I do think it has one of the best storylines of any game (and one of the best twists), I don't think it actually did much for furthering the way stories are told in games. It did much the same things with character interactions that RPGs have been using for a while. Although the extra insights you'd get as a Malkavian were quite interesting.
