Well, there are discussions about such things but I’d be curious how many would cite storage space concerns as a reason for not buying a game (I certainly have though). Ultimately gamers (especially PC gamers) welcome yearly improved graphics and monitor resolutions aren’t decreasing in size so assets for these AAA titles can become large.
That said, sometimes it’s not the graphical game assets themselves causing the filesize increase but things like pre-rendered cutscenes (video files) or uncompressed audio (to save some processing power IIRC?). Nier: Automata, a mid-budget Japanese title which was around 44GB installed, had pre-rendered cutscenes that consumed something like 40GB alone—which weren’t even in 1080p and had stuttering issues. Great game though.
