Yeah, PC games were more rough, but they also often had a mechanism for updates. Sometimes it was a physical expansion pack (I think Warcraft 2 and StarCraft expansions were distributed that way, I forget though), and some had an online updater (I had dialup for most of my childhood so I am very aware of how much that sucked).
However, since I mostly played larger titles, I didn’t have to deal with that. Some games I loved as a kid:
- Dark Forces
- Lords of the Realm 2
- Command and Conquer - most titles
- Warcraft - 1&2
- Age of Empires
- Rainbow Six: Rogue Spear
I don’t remember any kind of patching needed for those games, and these were all mid to late 90s games, and I also played a lot of older floppy games, like ZZT and Scorched Earth, though the latter saw plenty of updates (I think my brother downloaded them at school or something).
Sometime after 2000 or so games started relying on downloading updates on PC, and with the PS3 and Xbox 360, that moved to consoles as well.
