In 3 ~ 5 years 4K will be standard.
Many players will expect a 4K downloadable texture pack for games which will easily rise games install size to above 100GB.
For now nobody cares, but soon PS4 and XBox will support full 4K gaming and Pc will just follow the trend.
Nintendo will stay on low resolution tho.
The PS4 and XBO use Bluray discs, which are up to 50 GB. There’s several games that reach 100 GBs after downloadable content gets installed.
Physical sales for PC games are practically non-existent in most of the major markets. But even before CD/DVD games died, most games would have you install multiple discs at the start, and then only use 1 disc to play off of.
so in these years i could create an game for pc with maybe 50 gb content, which i could offer to the market within a tray including 1 blueray (dual layer)?
