Children Follow Same Steps To Learn Vocabulary, Regardless of Language Spoken

This is an interesting bit of research. When learning languages, children learn nouns first, verbs second, and adjectives third. They learn about things, followed by actions, followed by modifiers.

When teaching a player how to play your game, this might be a basic way to predict what your player wants to know in what order. They want to know about the setting first: they want to know the names of things, to familiarize themselves with their surroundings. Then, they want to know what they can do within that setting, what actions they can take. Then, they'll bother themselves with the subtleties of your systems: what is strategy but a modifier on a straightforward action?

Something to think about.
