Well thats the thing we cant include anything because Yobmod claims we can only use themes that are exclusive to science fiction which is just absurd because all science fiction themes can be used in fantasy which can be called sci fantasy but Yobmod refuses to list horror another which Yobmod refuses to list and surreal comedy For political structures I added two Ecology and Economics and cited them both and Yobmod deleted them If you check the history of this page others edited it but they didnt edit out any of the things Yobmod did as they or at least I know that they can be science fiction themes So I think that the only way Yobmod will be happy is if we stick with the edit I just made
