Watching lots of Doom videos on Youtube helped me learn some aspects of the game surprisingly fast. I can't control Doomguy as fast and as precisely as the best Doom youtubers but I can read a situation in the game about as fast and as good as they can and often come up with the plan they eventually follow faster than they do.
I get it! Years ago my obsession was Classic Tetris, and it was common knowledge that watching skilled players at work would improve your own stacking and strategy. A lot of the pros openly admitted to watching their competition while starting out in order to get good
Later I became obsessed with Argentine tango. Unfortunately, I thought, "comprehensible input" won't work with dancing, especially not a couple's dance. Nevertheless, unable to dance every day due to my local scene being quite small, I instead consumed a boatload of YouTube videos during my spare time. Instructional content, performances, class summaries, and what have you. And I progressed super quickly.
First off, as a leader, it is good to have seen competent dancers with good musicality and how they choose their steps to fit with phrases of songs. That much fits in parallel with input-based language acquisition techniques. But I also think I gained a good amound of intuition about how to move my own body. Not perfect intuition, but more than nothing, which was very much my starting point.
