It’s also just a game. No one needs it to be productive.

Edit, ok actually looked at Mindustry. It looks fun, but it’s also nothing like Factorio. Don’t know why you brought it up.

Besides, even if Factorio isn’t open source, it is available for Linux as a DMR free download. We should be supporting it.

Open source is more important for productivity software. Servers, Office Suites, Graphics and Game Engines. The game itself isn’t as important for opensource, as a game company changing the play mechanics wont effect someone’s income.
