Life is not logical.
It is random, unfair, and often impossible to optimize.
In just one month, I built more than ten simple life simulation games.
They simulate money, health, happiness, inflation, aging, luck, and failure.
All of them are free. Most of them are brutally honest.
This article explains why I built them — not as a hobby, not as a game developer, but as someone trying to survive.
I am not a game creator.
I am a person with depression and a developmental disorder.
In nine months, I will lose my job.
I do not have savings that can support me long-term.
What I needed was not motivation or inspiration.
What I needed was a way to live.
Writing long articles did not scale.
Serious apps required skills I do not have.
So I chose the only thing I could build quickly:
Simple simulations that visualize life itself.
Why simulations?
Because life is already a simulation.
You earn money.
You lose money.
You get sick.
You recover — or you don’t.
Random events change everything.
No amount of effort guarantees success.
No amount of caution guarantees safety.
A simulation can show this honestly.
Not as advice, not as motivation — but as experience.
My design philosophy is extremely simple.
- One click advances one year
- Numbers change
- A graph tells the truth
That’s all.
No complex UI.
No long tutorials.
No “you can win if you try harder”.
Just time, randomness, and consequences.
Why build so many in such a short time?
Because survival does not wait.
Each simulator explores the same life from a different angle:
- Inflation slowly destroying savings
- Investment decisions compounding over decades
- Random life events ending a run early
- Perfect systems becoming meaningless
They are variations of the same question:
“Can you survive this life?”
These games are not optimistic.
Some of them are intentionally unfair.
Some are impossible to clear.
Some allow success by doing almost nothing.
That is not a bug.
That is reality.
Life does not reward balance.
It only reveals outcomes.
This is not therapy.
I am not trying to heal myself or others.
I am not giving advice.
I am simply externalizing my thoughts into systems.
If someone finds comfort, insight, or fear in them — that is incidental.
Finally, about money.
Yes, these games link to my blog.
Yes, I rely on ads and affiliate income.
Yes, I need traffic to survive.
This is not a marketing story.
This is a survival record.
If even one of these simulations becomes useful to someone,
and that leads them to another,
that is enough.
I build simple life simulation games
because life itself is already complex enough.

If you leave this page thinking a little differently about time, money, or life,
then the simulation worked.
