The Witcher III: Wild Hunt is a modern classic, a game that stands shoulder to shoulder with the greatest games ever made, games such as Planescape Torment, Baldur's Gate 2, Deus Ex or Vampire Bloodlines. I have no doubt people will still be talking about it and playing in in 15 years much like we are still playing Baldur's Gate (new expansion for it is coming, btw 17 years after release!).
Good on Gamespot for recognizing that and awarding the game and its studio accordingly. CD Projekt have been a consistent gold standard and I am very happy for them.
That said, I do have a few disagreements with the list overall. I would drop Evolve, Assassin's Creed Syndicate and Just Cause 3. I would add Life is Strange (somewhere into TOP 5) as well as place SOMA much higher. I would drop Fallout 4 much lower.
I would add Pillars of Eternity and Shadowrun.
But overall it is a good list. The inclusion of some offbeat games is pleasant, namely Kerbal Space Program and Cities Skylines .
Fallout 4 has terrible quest design (there are few good quests in a sea of shit) and mostly mediocre-to-bad writing. Many people find it unsatisfactory after Fallout New Vegas and particularly Witcher 3. Me included.
