Mechanics or flavour first?
(ttrpg.network)
I usually start with a very broad flavour concept, then figure out how to do it in mechanics, and use that to flesh out the details of the flavour.
There have been times when I've come up with a very detailed flavour first and then gone for mechanics later.
The only time I start with mechanics is with one-shots or other times I don't particularly care about the character themselves.
