I'm featuring the building mode here as a first video, since it's probably the most dominant part of the game that you can already experience in the demo.
Avorion is a space sandbox that takes various sandbox aspects from games like the X games or Freelancer, combines them with co-op multiplayer and lets you build your own ships. While the building mode is powerful, Avorion focuses more on actually doing things with your ship, flying around, fighting, quests and boss fights.
This is my first ever youtube commentary video, so I apologize if the quality isn't perfect, I'm still working on my speaking performance. And the mic wasn't the best either.
