How to create a REAL virtual world!

Kinda confusing…REAL …VIRTUAL…leave it.

Hey Guys!
Now, here’s the question I have been asking from a century…
How to actually create a virtual world kinda game with Unity free ?
Now, if you gonna stop it answering-
“There no specific way to create a virtual…”

I just kinda want some tutorials for a beginner as to HOW to code a game like that…

BTW, you can take for example.
Its made with unity, and I love it!

You want to make a game like MonkeyQuest? Well, see How can I start learning Unity fast? ( List Of Tutorials ) - Unity Answers.
