As much as any other track. While their layouts might be on the simpler side. There is still abit of work to create the track and the surrounding area. Creating Wunstorf would be faster then creating, let say Sebring. However, Sebring would most likely sell better then what Wunstorf would do. In the end, there are only so many work hours. The time they spend working on one track is time they can't spend on other tracks. Would it be fun to be able to do a complete historic season, definetly. Are these tracks the best additions to Raceroom, probably not. In the end it depends entirely on what plans sector3 and raceroom have for the future.
