What this is

Not a quiz. Not a personality test.

Each run is a branching story built from decisions people actually face. Pick an archetype, work through seven chapters, and watch four things move as you choose: your skill, your money, your reputation, and your wellbeing. There is no score and no right answer — only the ending your choices earned, and an honest read on what that pattern costs.

Choose by topic

What kind of decision do you want to practise?

Each run includes a case file that separates the fictional outcome from the real decision concepts, plus a related guide or quiz for further study.

Finance decisions

Fictional shocks and trade-offs that practise documenting constraints, separating facts from assumptions, and slowing down consequential money decisions.

Money & risk

The Bonus

It landed. Now it has to go somewhere.

A seven-chapter branching run through an annual bonus: the number that is smaller than announced, the upgrade you have been postponing, the pension nobody mentions, and the twelve months that reveal whether it changed anything.

What it teaches: planning a one-off payment without treating it as recurring income

Money & risk

The Pay Cut

Less money arrives. The bills do not care why.

A seven-chapter branching run through an income drop: the announcement, the triage, the conversations you avoid, and the eighteen months it takes to find out whether you handled it. Four archetypes, six endings.

What it teaches: what to clarify in the first ninety days after an income drop

7 chapters · 6 endings

Technology & engineering

Release, migration, and disclosure scenarios about evidence, ownership, rollback plans, and working through authorised processes.

Engineering & judgement

The Disclosure

You found it. Now the hard part starts.

A seven-chapter branching run through finding a serious vulnerability: who you tell, how fast, what you say publicly, and what happens when the vendor stops replying. Four archetypes, six endings.

What it teaches: authorisation comes before a disclosure timeline

Engineering & judgement

The Rewrite

Nobody understands it. Everybody depends on it.

A seven-chapter branching run through a legacy system: the module everyone avoids, the rewrite that sounds obvious, the migration nobody budgeted, and the point where you find out whether you improved anything.

What it teaches: learning what a legacy system does before replacing it

7 chapters · 6 endings

Civic & public decisions

Negotiation and turnout scenarios that foreground procedure, official sources, privacy, uncertainty, and non-partisan limits.
