little possibility for pandora there is, i think
i don't wan't to talk about future releases... makes not a lot sense to me.
but "arisata" for fe2 could be a advice how to start it. i never tried something like it for ffe and hardly managed to do some edits for fe2 myself (he didn't described it to well). only the few predefinied systems are possible to edit. but try if you dare, we will all be curious for the result.
further you can alternate easely the predefinied names or "object" names list. check that imperial,alliance and federal names are generated from different "sets". if you like to fit the game a little bit to your sci-fi universe.
yes, some well known authors/works are allready present (they read the same books as we did, etc)
