The games from '90s that are still remembered are the best ones. There were a lot of games that were slow and bloated for that time. In the '90s we've wondered why did the '80s games were so efficient. Games that used to run on 64KB of RAM or fit on floppy needed CD-ROMs and megs of RAM. This hardware was not considered small — it was huge compared to 8- and 16-bit computers and consoles before it.
At that time PC did not have hardware-accelerated scrolling and sprites like consoles and Amiga, so many PC ports of console games had higher hardware requirements and lower fps.
Windows 95 did not have a reputation of a small OS. It was seen as a complete waste of RAM for MS-DOS games. Microsoft had to invest a lot of effort to turn that around (with DirectX).
It's a matter of perspective. You can already wonder how Portal 2 is so small compared to multi-GB games. In 30 years when GTA 6 comes out with 7TB day-one patch, we're going to marvel how GTA 5 could fit in mere 30GB.
