According to sources, Galen Merek (Starkiller) was born in 19 BBY, FU started in 3 BBY and he died in 2 BBY aboard the Death Star I. That would make FU2 take place sometime between 2 BBY and 0 BBY. How does the lucasarts team think there's still 20 years to do FU3 until the start of A New Hope when all three movies take place in 0 BBY?
