Epic sometimes is a freight container ship operated like a speedboat.
There’s still some time left under launch, this is honestly something that could be clearer on the Unreal Marketplace as well. As the current license stands, it says “plugins may be licensed on a per-seat basis”, yet whether which way that may swings is not something that’s immediately clear on the store page. It doesn’t make sense for all plugins to be licensed on a per-seat basis because anything with any c++ will have to be a plugin, so sometimes stuff that isn’t really a plugin are distributed as a plugin because of few lines of c++.
