It wasn't exactly what I was asking, but they were excellent about the secondary characters.I really don't get the question that you trying to ask.
but from what I get is "side character 101 (?)"
if that's right, then:
1. make it not too outshining your mc.
2. race doesn't matter (I think) just make him a really likeable dude, but remember, come back to number 1.
3. good side character tend to have some kind of backstory, make it to be somehow linked to the mc existence (for example your side character is lonely man, and boom mc appear, idk)
4. unless you make NTR or blackmailing story always stick to the supporting rule, people really annoyed at inconsistency of a character, let alone the one that close to the mc.
I think that's it, that was my take on side character.
good luck with your game or story.
yeah I think this what he mean..I think the question is regarding background characters, which some game devs just render as black silhouette.

it is a very sincere opinion, thank you for taking the time to do this, i really appreciate that you are careful with the games, I notice carefully the details of the scenes.I believe devs render the black silhouettes simply to reduce render times, not to enhance the game in any way. Simply a developmental shortcut to make the locations appear populated rather than empty.
If this is what you are referring too, I honestly don't think it matters in any way. Do what you want to do in this scenario. If you want to speed up rendering speeds, do it. If you find that you prefer actual background characters you can do that as well. I honestly don't believe the players will care in either scenario.
