If you have Supreme Commander: Forged Alliance, the standalone expansion to the original game, make sure to download the community-run Forged Alliance Forever (FAF) client.
A lot of quality of life changes, optimizations, better network code, mod support, custom maps released almost daily by the community, and it’s still actively played online even after twelve years.
All it needs is a copy of the game to verify, and it goes regularly on sale on Steam.
I like to play against the cheating AIx with one of my friends, and it never seems to get old.
I like the analogy that Lemmy is like an email provider. Many possible providers, one Internet. Maybe we could get more traction if Lemmy were promoted in a similar manner? Or even have email service like sdf.org?
