Ha! It's interesting how you only posted the most vague part of the answer previously to support yourself. Now lets look at the first sentence in the answer where the word "video game" is specified (because that's what we're discussing after all, isn't it?)
An open world is a type of video game level design where a player can roam freely through a virtual world and is given considerable freedom in choosing how or when to approach objectives.
Is there a virtual world you can explore?
Is there freedom in choosing how or when to approach certain objectives? (underlined "when" because no game emphasized on that more than Majora's Mask)
