I'd always believed that the price of a game is mostly based on the perceived demand for the title.
If a $60 dollars game is in high demand and selling well, isn't it pointless to argue about development costs and what not?
Now talking about graphics, i believe that we reached a point where a game can look as close to it's original design intent as possible.
You want a Adventure game looking photorealistic?
There's Uncharted 4 for you!
What about a whole South Park episode where you can play as a RPG that looks EXACTLY like the show?
South Park: Stick of Truth, Baby!
Wait, you want a pixelated 2D platformer with great controls and a outstanding soundtrack that reminds your childhood?
Shovel Knight.. Bum..
Octopath Traveller looks great for what it is trying to achieve with its visuals IMO. There's little room to improve it without shifting to a whole different game philosophy on the graphics. :p (again, that's only the way i see it)
