Tutorial videos are of some importance in helping to teach people the often involved game mechanics of this branch of Simutrans (I believe that absolute block signalling is next on the list), but they can take a terribly long time to create. Nearly half that time, however, is taken in the process of creating and setting up the saved games.
If there is someone who is willing to assist with that aspect, it would make producing tutorial videos a great deal easier. The way that I imagine that it would work is that I should write the script and send it to the person who volunteered to help, who would then send in return a set of saved games set up ready to record both as to place and time (a good few seconds in advance of where the recording needs to start in each case) based on what is being described in the various parts of the script, with plenty of scope for recording incidental visuals for more general narration (e.g. the introduction).
If anyone is interested in assisting in this way, please let me know.
