Work with a Publisher or Investor to pay you to finish the game in exchange for a cut of the revenue or equity in the studio.
You have 5 seconds to impress a publisher. The two most important things
If the publisher is not impressed, or the game does not align with their catalogue of games they publish, you will get rejected.
If you make it past the initial impression, they will look into the studio / team background. If your team is capable, they will likely negotiate a deal.
Dont be the idea guy and just ask for money to make a prototype with no prior background.
Publishers will draft the inital contract with terms that are favorable to them. You also want to verify the expectations and deliverables from both your team and the publisher. It's highly advised to review the contract and to consult a lawyer on the terms.
The Top 5 things to have in a publishing contract are:
Investors are business partners, not business savers. Investors invest in something that is already proven to make money or grow an audience. Then, the investor will help you take it to the next level.
The revenue from initial sales should cover initial costs. You will need investors if you want to make future investments or leap into a bigger market. Demonstrate that your business is already successful and stay successful. If the investor wants to help with the process, they can join. Nobody wants to get on a train that hasn’t started. They want to get on a train that’s about to leave the station.
