ElB0ludo | Metroid: Zero Mission - Is reverse Tourian viable on Normal mode RTA? @ElB0ludo | Uploaded 3 years ago | Updated 1 hour ago
Yes, the title of the video is clickbait. But I didn't want to spoil the ending.

This is tool-assisted. For more information, go to http://tasvideos.org

This was played on 50% speed and using savestates, but only once at the beginning of every room. My intention was to simulate a "perfect human viable play", using only what a believe to be RTA-viable strats, by repeating each individual room until they seemed errorless. Obviously, there is still room for very small optimizations, but I believe my final result to be very generous regardless, using some somewhat hard strats and more-precise-than-usual movement. I don't think that any more RTA-viable optimizations would change the final outcome anyway.

I recently got a comment on my old Alternative Tourian Escape LOTAD video (youtu.be/q1e3-Njihew) by user The Sedaiv saying that some day humans would be able of doing that on a real console.
As much as I would like to see that, I highly doubt it will ever happen. And to prove my point, I made this.

I think that, to do a run as good as this video, it would take tenths of thousands of attempts, and beyond human skill or suspicous luck; and as you can see, it wouldn't be enough. I don't believe anybody would be willing to put so much effort into something like this either.
In the end, I don't believe humans will reach TAS levels ever. Of course, I do believe humans get better and better with practice, being able to pull off strats once believed to be TAS-only at specific and isolated points of a speedrun. But there's a limit to human skill, and no one can play absolutely perfectly for as long as 2 minutes straight. But that's the beauty of TASing: knowing that something is possible, but no one will ever do it.

(Also, I should have done a human theory TAS insted of this... Oh, well!)
