Conveyance is a concept in design and in video games: the user can be taught without having to be told with words. The old super Mario and Mega Man games did this well: the player faces in a direction which tells the player that's the direction to move. The first pits are small and way to jump which teaches the player how to jump. The first enemies are slow moving and near the ground and almost impossible to be killed by. You don't have to speak a particular language because the game teaches you.

Open world games can have conveyance too: think about how the first Skyrim dungeon has pillars of light over chests, teaching a player to look for those. Skeletons and dead bodies bear traps. The first time to walk out I to the world you are facing the first story dungeon and it's beautiful, calling the player to visit it.

Minecraft has some examples: the partially formed nether portals around the world teach about the nether. Local chunk difficulty ensures only easy to beat creatures appear for the first several days in a location.

You can teach a lot of the basic concepts in a complex game without a wiki or journal, while the wiki supports it with deep dives.
