Older games were so ridiculously short and oftentimes you'd just play the same game over and over again which is why they ended up being memorable experiences. Remember VTM: Bloodlines? It took like 2 hours to complete, but at that time you'd just replay the hell out of it with different clans and different factions. Fallout 1 had like 10 quests but you'd research every nuke and cranny over there. In Morrowind you were actually fucking reading the ingame books.
And there was no internet so you couldn't google the walkthroughs to pass levels with terrible game designs and when you've finally finished those levels you actually felt acomplished (Again with Bloodlines, those fucking sewers), something that's impossible to embrace today in a single player game.
If games with that much content were released today the devs would be hanged (unless they advertised them as hipster indie bs).
