I'm pretty new to D&D but it seems like a really fun game. I've played a little and DMed once. I really enjoyed DMing and people seemed to think it was pretty cool. The only problem is: it was one dungeon. I love being creative and have a lot of good ideas but I'm lost on how to even start creating a world. I've read the DMG and seen what it had to say but still feel overwhelmed. Does anyone have ideas on where to start? I'd really appreciate it.
