alt Hacker News> The game is not expected to be made open source due to certain dependencies that are not also open source.
That's always kind of struck me as a silly excuse. So just release it without those non-open source dependencies. If there is a community need, they will be re-implemented. There's no law that says an open source release needs to be buildable from day one.
The only time it's not silly is when said dependencies are not just non-free, but covered under an NDA. If the API is under NDA then they can't release the code that uses the APIs. AIUI this is why FOSS games don't get ported to console, even though there might be people willing to fork up the money to pay for devkits and SDKs.
