Nope! Do I need a fleet of servers to run it? No problem! Do I need a specific release.minor.patch of FreeBSD? No problem! Do I need your proprietary kernel patches? Yeah you need to release those.
Or do you have tooling that allows your devs to run it on their machines without the server components (most online games do)? Releasing that instead is also an option.
