How about bringing back a classic SF series call Perry Rhodan? There are over 3000 stories published in the series but in German. Ace books brought about 137 to the United States. Those have been out of print since the 1970's. I would not mind having those in print again - they are tough to track down. Not having this series in English is a tragedy. So gear up and restart a PerryVerse invasion in the U.S.!
