Preparing a business plan for a game on Steam

Earning millions is easier than ever. I'll tell you how :-D

Earning millions is easier than ever. I'll tell you how :-D

When I posted my final presentation [ru] (slides) for World Builders 2023 (my posts, site), I promised to tell how I made a roadmap and a financial model for the game. So, here they are.

At the end of this post, we will have:

  • A brief strategy of our company: what we do, how, and why.
  • A table with our beacons — successful games roughly similar to what we want to make. Similar in gameplay, team size, budget, etc.
  • A composition of the team we need to assemble.
  • A roadmap — a development plan for our game.
  • An outline of our marketing strategy.
  • A financial model — how much we will spend, how much we will earn.
  • A large number of my caveats throughout the post.
  • Jokes and I hope witty remarks.

All the final documents can be found here.
