Honestly? I don't think so. There's a reason why so many level designers at some point become game directors, etc. - Level Design is so extremely underrated. The people who decide what you're actually doing moment to moment are the ones that are in charge of how much fun the game is. So if your game is full of bad level design, I'd argue that the game itself can't be all that fun.
This is always the problem with open world games. Players are usually free to go wherever they want, so you might just get unlucky and run into a super boring stretch right from the get-go.
I remember getting so much shit here on GAF for saying the same exact thing when No Man's Sky first released, that even though it's a cool gimmick to throw out 'We made 17 quintillion planets!', it's not all that fun to run around empty, procedurally generated stuff. And it really wasn't. We see this same shitty movie play out in the same exact way again and again and again and every single time another developer pulls the 'Our world is 526.000 square kilometers big!' bullshit move, gamers fall for it again and again.
I can open Unity right now and create the biggest open world terrain the world has ever seen. Wanna play it?
