Worst game ever is definitely subjective. This definitely highlights how a lot of games back then if they weren’t simple arcade style games were extremely hard to figure out without the manual, it was definitely a part of the experience. ET is often cited as the worst game of all time and one of the reasons is because it was cryptic like this and relied on needing the manual to play it properly, but it was clearly a game marketed to kids. But something like Myst is hailed as a great game when it is a very cryptic game. I suppose that at least everything you need to complete that game is in the game itself, I suppose that’s one way of looking at it, also the fact that it is targeted to an older demographic that already has familiarity with complex concepts in games.
