1. Introduction

We are making an open-source game engine, 3D and 2D, with comfortable visual editor and a powerful API. We proudly cooperate with open standards (X3D, glTF). We like modern Pascal, continuous integration, being cross-platform (desktop, mobile, consoles, soon web). We’re passionate about open-source and free software and tools to design engaging stories in the form of computer games.

The primary goal of your donations is to give us time to spend on the engine development. More time translates to more features, faster. By 2024, Michalis Kamburelis, the lead engine developer, spent most of his life on the engine and doesn’t plan to stop :) Moreover, since May 2024, Michalis works on the engine full-time counting only on your support. So anything you can give is really appreciated!

2. How to donate

2.1. Patreon

The suggested method of donating is to support us on Patreon.

We offer a few perks, including these cool stickers!

2.2. Open Collective

Another option is to support us on Open Collective.

For regular people, this is similar to Patreon. You can easily donate monthly or one-time.
For companies, this is how you can cooperate with Castle Game Engine as a company.

First of all, contact Michalis ([email protected]) and tell me what do you need. Support, priority fixes, consulting about engine usage? Specific engine features to meet your use-cases? We can discuss it all.

Then you can pay for this work, and get a formal invoice for your company, through Open Source Collective. The gist of it is that Castle Game Engine can formally act as a (US-based) company, in particular we can issue invoices for your accounting and tax needs.

2.3. GitHub Sponsors

Another option is to support us by becoming Castle Game Engine Sponsor on GitHub.

2.4. PayPal

You can donate directly using PayPal. You can pay directly using your credit card, or use a PayPal account.
