The best games have already been made.
Imagine you made that statement on May 27, 2019, the day before Outer Wilds came out.
Given that movie theaters sprang up in the early 20th century, [2] you could make the argument that video games haven't even reached their equivalent of the French New Wave yet. Given how far someone can go with a little bit of self-taught asset creation, I think the best video games will be made after you and I have passed away.
So hard disagree there.
If all you look at is AAA experiences, then maybe I can understand this viewpoint, but this is absolutely not true in general.
