Ignoring the lack of updates if the game is buggy, games back then were also more focused on quality and make gamers replay the game with unlockable features based on skills, not money. I can't count the number of times I played Metal Gear Solid games over and over to unlock new features playing the hardest difficulty and with handicap features, and also to find Easter eggs. Speaking of Easter eggs, you'd lose a number of hours exploring every nook and cranny finding them!
Kids these days have no idea how easy they have it. Tracking down a driver update or patch (that you just moved to an unencrypted folder) on a dial-up connection? Re-installing your OS from a series of floppy disks because something broke, again? Limiting clock speed because so many things were tied to CPU cycles and wouldn't function on new hardware?
PC gaming was a nightmare but you put up with it because StarCraft or Quake 3 online was dope as hell, we had Diablo and Myst and Half-Life and Doom and Putt-Putt Goes to the Goddamned Moon so it was all worth it.
I remember the day I learned this lesson.
Young gamers don't know the pain of a BSOD and the interminable wait getting back into game on an IDE hard drive. Even a CTD was a nightmare.
