๐ The story
A roll of the dice decides who your Sim *is* โ and you don't get a say. Gloomy, slob, hates children? That's your protagonist now, warts and all, and you'll play every awkward, ill-matched moment exactly as fate dealt it.
๐ The goal
Let a random roll decide your Sim's **traits and aspiration**, then play strictly to them for a whole life.

SimsOne Sim, randomly rolled
๐ Getting started
- Roll three traits and an aspiration (a dice app, or CAS randomise), assign them, and never change them.
- Randomly determine traits + aspiration; lock them in.
โจ๏ธ Cheats to type
testingcheats true๐ General rules
- Traits and aspiration are rolled, not chosen.
- No swapping out traits you dislike.
- Play in line with them โ let them genuinely steer decisions.
โจ Specific rules
- The rolled aspiration must be completed (or honestly attempted) over the life.
- Career and lifestyle should suit the rolled traits.
- Awkward combinations are played, not avoided.
โ What you can do
- Use a random roll for traits and aspiration, then build the Sim to match.
- Use `bb.moveobjects`.
โ What you can't do
- No changing the rolled traits or aspiration, and no re-rolling ones you dislike.
- Play the whole life true to the roll.

๐ก Strategy tips
- Lean into clashing traits for story โ a Loner with the Friend of the World aspiration is a great arc.
- Pick a career that *fits* the roll rather than fighting it; the constraint is the point.
- Roleplay reactions to whims and moodlets the traits generate, instead of overriding them.
