Agreed. I've been trying to get into it multiple times in the past years since I somewhat "sense" it's a great game, but the lack of decent in-game tutorials and game guides/videos has put me off it every single time I tried it. 

Definitely... Quill18 spiked Aurora 4X's popularity, and that game makes Simutrans look like GTA5!

Really any Simutrans content on YouTube would help, there are very few good videos up there. It's the only game I've ever considered doing a video on because it's just such an underrated gem.

The German youtuber tom.io has brought some new people to the game (including myself)... But it seems that there is not very much to see in English.
His [first series](https://www.youtube.com/watch?v=YBwzjNO9mww&index=1&list=PLkT9jnAPqQv5Yb55hN4p5stRejHAzHtwW) was on Pak128, he also did a [second series](https://www.youtube.com/watch?v=HKRuNjawhwU&list=PLkT9jnAPqQv6bDxAKWvXLcxtM5tmuNPF-&index=1) on Pak192.Comic.

You know, if anything could cause a major upwards spike in this game's popularity, it'd be a large youtuber/streamer showcasing it.
