7.: Knights of the Old Republic
On paper this sounded almost too good to be true. BioWare, the people who made the award winning Baldur’s Gate games that revitalized the roleplaying genre were to make a Star Wars game, and in order to get out of the way of all the established things and especially the movies, they would set this game 4.000 years before the events of A New Hope. What happened was that BioWare etched out their very own niche in the official Star Wars universe and populated it with a ton of memorable characters.
Knights of the Old Republic became the stepstone for a whole new franchise and eventually led to the creation of the Mass Effect games. In and on itself it introduced a dual morality system to RPGs by letting players choose between the Light and the Dark Side of the Force.
