Homie, I’m sorry but open world really just means its one map and it implies you might be able to go anywhere on the horizon. Rain World has an open world, Elder Scrolls definitely does except for Arena, pretty much any MMO, Astroneer, your OLD GAME No Man’s Sky is open world. Seriously take a step back from your own project and breath for 4 hours before making announcements. That being said, Light No Fire looks ridiculously good and I can’t wait for it.
