The only time character customisation affected a game I played was mass effect and that just gave you an additional mission based off it.
Most if not all of it is simply aesthetics of how you want your character to look to having their own backstory, which 4/10 makes you fantasy Batman.
The last time in terms of build it affected how I played was Fallout NV, there I actually made one build for early game to beat speech checks in the first mission then used the 'are you sure you want this build as you leave the starter town' to respec. Fallout 4 ruined that to where I just abuse the leveling glitch thanks to the autonotron dlc to get everything I want.
