2. The Legend of Zelda: Breath of the Wild (4 points)
Conversely, BotW is by far the most prominent example of the open-world adventure which has been the most prominent style of single-player gaming. Again, many other games could've gone in here, like Skyrim or The Witcher, but Breath of the Wild is the new standard every game will be looking to emulate, and is currently the average gamer's favorite game ever, so, yeah.
How would you even get such data? What is your source?
I'm not sure what you're trying to say with that "most prominent" line. Skyrim has sold over 30 million copies and Witcher 3 over 20 million. I would imagine they'll be every bit as influential to the open-world RPG genre as Breath of the Wild, at the very least.
