akyuuBattle for Wesnoth: open-source, turn-based strategy game
Highly suggest connecting with one of the lead developers, Charles Dang/Vultraz, if you have any C++ jobs in the USA.
He's been a developer on Wesnoth since 2012 but only graduated university in 2024. Unfortunately, it's been an absolutely brutal market for new graduates. Even if you're a maintainer on one of the most popular OSS C++ projects on GitHub.
I can't recommend him enough.

I am very surprised if he can't find a job, as an American, in DC, with 12 years of C++ experience. Sure companies aren't great at assessing open source experience, but there is one area its easy to find a job as a dev: work that requires a clearance.
