The premise

Get there first. Get out alive.

You found a company together with a few other ambitious minds. What you lack is money. Rumor says a dead killer kept a hoard in a cave outside town, and you are not the only ones who heard it.

Thirty soldiers are on the road to take it. You have a head start and very little else. Every room you open and every risk you take is a choice between more capital and a way home.

Petter Fornes wrote, designed and laid out the game himself in Trondheim. It plays like a classic OSR adventure, with a company sheet next to the character sheet.

The question at the heart of it

Can your Company secure enough capital to survive?

Whatever you carry out of the cave becomes your capital. The last roll of the night decides the answer.
How it plays

One evening, one company, one roll

1

Found the company

Make characters and fill in the company sheet together. Who you are, what you want to build and what you are willing to risk for it.

2

Go get the money

Play the starting adventure, Christman and the Devil. Clear procedures, low friction and real danger, with the soldiers getting closer.

3

The final roll

Count what you carried out. One roll on your capital decides the fate of the company: success, failure or something in between.

Questions

Before you buy

Do I need Into the Odd to play?

No. Gründer is a complete game. The 24-page rulebook has everything, and it uses the Into the Odd rules by Chris McDowall, so if you know Cairn, Mausritter or Mythic Bastionland you already know how it plays.

Is it really about business?

Only at the edges. At the table it plays like a classic OSR adventure: a cave, a hoard, a clock running out. The business part is the reason you go in, and the last roll at the end.

How long does a game take?

One evening. Gründer is built as a one-shot, and the session ends with the final roll that decides the fate of the company.

How many players?

Three to six, plus a GM.

Is it available in print?

Yes. A5 softcover in full colour, print on demand from DriveThruRPG, and in selected game shops. Shops can order at retailer terms on the vendor page.

Was AI used to make it?

No. Text, layout and editing are made by people, and the art is public domain.
