I actually have a rough character concept for every subclass and (almost) every subrace all laid out on my spreadsheet (I know, I'm sad!), and I don't rule out eventually completing the 46 playthroughs it would require. After all, I'm still playing BG1 & BG2 after more than two decades, so why not BG3 as well

I'll definitely complete at least one playthrough for each race, including the short ones.
But my first playthrough is a Tiefling Rogue/Sorceror multiclass, so I'm probably erring towards the side of predictability so far. But I'm okay with that!
