After I made my character (which was fun!), I enjoyed walking around the huge area and trying to find chests and discover all the merchants. I got some folks on my team and grinded a bit.
To be honest, I got a really strong 'ESO/Skyrim' kind of vibe, in that I felt like the world was huge and I was meant to explore naturally, so I hope that's the kind of open world experience you might be working towards!
I didn't find another map than the main large, bustling desert city, and didn't see any quests.
Thank you for the submission ^^
