To my limited knowledge, Perry Rhodan is about
the most popular SF series on the planet (in terms of book sales). There is (or was) a new novel published every week (by different authors under various pen names), IIRC. I only have one book, "Jubilaeumsband," in commemoration of the 1000th novel printed in the series (and it dates from 1980). I'd think that anyone attempting to adapt all of it to SE4 would have a massive task in front of them!
