There is a point when the game just adds graphics and not content. Current triple A games are going that way, the problem is I just play indie games so I really doubt an indie team has enough time to add that much detail to their game
This is one of the reasons why i also sitck more to indie and old titles instead of AAA, it's at a point that we have games launching all the time but only 2 or maybe 3 every year are actually good
Honestly, i still can see it becoming a thing in a decade, we already have a good amount of 100GB+ games here and there, and as storage becomes cheaper, the less we will care about a feel hundred gigabytes, i remember when having a 8GB usb stick was more storage than you could dream of
When I was a kid, the first PC game I played was Civilization 1 and it came with 4 floppy discs, so less then 10 MB. Some years later it seemed crazy to me that most games come on a CD-ROM disk and require 650 MB of space. Now I am playing games that ask for 100 GB and it seems fine to me.
It wouldn't surprise me if 10 years from now 300GB would be the norm
