I know I would love to have heroes.. or fleet commanders. Even if they were randomized and all that jazz. I'd also like more than one leader per civilization. If anyone has ever played Europa Universalis, you'll know that each army has a generic randomized leader with the same stats (and sometimes you'll get historical leaders that the developers made with special stats).
That's what I wish GalCiv2 had, even if they were only generic leaders or just something we could write in ourselves. The same for civilization leaders. The only way to get rid of them is through events, but their replacements usually have the generic name Azurelas for me for some reason. I wish they'd die of old age or maybe more events or even get overthrown/lose elections. It'd be even cooler, and I know I am reaching here, if political parties had leaders and whatnot. But I know this is ridiculous and hardly of interest to the developers.
Odd request, I know, but I like the immersion it adds (yes, I am such a dork when it comes to strategy games that I would likely create an entire cargo and crew manifest if I was given the tools

)
