As others might tell, I'm not big on "immersion" comments as, really, that's a personal thing and pretty varied. It's probably almost impossible to satisfy all immersion comments out there.
But I must admit there is one thing currently in the game that is slightly prickly to me and I thought I should bring it up. Some of the colonization events make absolutely no sense when playing as the Yor. While most of them are pretty neutral, some clearly refer to things like food or other biological concerns that mean absolutely nothing to a Synthetic Race. And a couple clearly imply, either in the opening text or in the choices, that you are a biological faction. Since being Synthetic is a race trait in GC III, this is probably going to come up quite a bit as Custom Races are made.
What I was wondering if it would be possible to either set aside some of the colonization events so they wouldn't apply to Synthetic races and/or create some colonization events that will only come up if triggered by a Synthetic faction.
If not, no big deal. I'll live with it. 
But it might be kinda cool to be able to do this at some point, if possible.
NOTE: The related point that others have brought up about conquering/acquiring a planet from a Synthetic race [or vice vera] isn't as important to me, as I can handwave that away with my own explanations. Which just goes to show just how personal immersion really is 
. The real problem here is, with colonization events it becomes much harder for me to explain something away that is directly being said to me as I can come up with my own explanations for something on a newly aquired planet since the game is silent on that point (the sythetics got fitted with food convertors or something/the organics got coverted to cyborgs, etc).
