Making a case of vocabulary learning via Minecraft videos and playing Minecraft.

A learner needs to encounter a vocabulary for more than seven times for incidental vocabulary learning to take place. The number of times of retrieval of a word meaning is what matters. With this in mind, after a closer look at one single Minecraft video, I found that some target vocabulary occur more than seven times (I'm not counting the function words).
For example, the word “lamp” is a required vocabulary listed in the elementary school English curriculum in Taiwan (which only occured 3 times in the textbook). The word "lamp" has occurred 26 times within several minutes in the video. My guess is that this would not normally occur in a National Geographic video where the narrative are usually pre-edited to be succinct and to the point. The Minecraft gamers’ monologues are spontaneous speech and contain redundancies that provide repeated exposure to certain vocabulary in a short amount of time.
Here's an example of the word "portal" that is mentioned repeatedly.
