[more discussion of space dolphins]
Yeah, I was just working off the assumption they happened to actually work in water (or that sentient dolphins had just always been around).
Back on topic, I'm wondering if the portraits are going to be paper-dolled clothes/paraphernalia with base colour changing options. Makes sense. Maybe 2-3 portraits a race, with 3-5 clothes options, coloured randomly (or perhaps in a base palette for that race's "hat"). It'd give a bit of variation anyway. Easier than hundreds of individual portraits certainly, and allows for clothed, unclothed, bejeweled or semi-cyborg variations of each base race.
The portraits all line up nicely pixel-wise for paper-dolling in any case.
I could swear one of the dev diaries touched on this too... ah - #6:
"Now, as you remember from last week’s diary, there are about a hundred different alien race portraits in the game. Thus, we initially felt that lesser leaders should not have actual portraits, because we could not possibly produce enough of them to provide the requisite variety. But then, the artists started to experiment with different backgrounds and clothes, which thankfully proved sufficient to allow all leaders to show a portrait.
The different types of leaders all use different sets of clothes. This helps increases variety, but also reinforces their role, with admirals having a militaristic uniform, governors being more casually dressed, and scientist being a bit more techy. Clothes are shared between some of the more similar species, because creating five unique apparels for each species is just an enormous amount of work. (Not all species wear clothes though; it would be odd if this was every alien race’s custom.)
I expect that humans will be by far the most popular race to play. Therefore, they are getting some special attention with different ethnicities, genders and hair styles. There is nothing stopping modders from doing the same for other races, of course! For example, the system could easily be used for other things, like an insect race where you have a multi tiered system, with one appearance for the ruler, a completely different morphology for your Pops, and a third for your leader characters..."
I guess this means that clothing-free species (e.g. the Blorg) might end without many different portraits?
