[@rush99999] If you want my advice, don't worry about controlling and making an entire world at first. I would say to get the hang of things, keep it simple. It can be a straight forward and linear dungeon crawl for everyone to get the hang of things. By keeping your scope limited you also limit how much things can go off beat or stray too far from your plan. Have a straight forward dungeon dive or similarly self contained somewhat isolated intro, see where that gets you and then you could expand from there.
