๐Ÿ“– 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.

๐Ÿ’ 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

๐Ÿš€ 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.

๐Ÿ“‹ 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.

โœจ 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.

โœ… 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.

๐Ÿ’ก 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.

๐Ÿ”ฅ Want it harder?

  • Roll a brand-new trait/aspiration set every life stage and adapt instantly.
  • Roll the Sim's career and home world too.
