Okay, so I have played through the tutorial in order to test it, and have taken the following notes. As always this is meant as constructive feedback, just assume that all things I don't mention are great
General suggestions:
1) Can you make the window pop up somewhere else than in the middle of the screen? It's obstructive there and it's irritating that you can move it somewhere else, but then once you click continue it will be in the center again. So I suggest to either remember where the previous window was, or at least display it somewhere in the top left. If neither is currently possible I would like to make a feature request to the OpenTTD devs to enable one of these two things.
2) General movement is never explained, e.g. how to move the window (right click and drag mouse, or use arrow keys). I know there are alternative movement schemes, but I'd say we can assume standard settings here.
I'd make a new chapter about this and show it before all others.
Things that could be shown in such a chapter:
- Moving the viewport
- Zooming out/in
- Using the map
- Using the town list to locate a specific town (conveniently, this could be the first town you use in the following chapter)
- But don't add any more / too much, to not make it boring before the "real" stuff starts.
In the following chapters you could then let the user navigate by himself more often. It's less disorienting than just jumping to the towns without warning. And if you must jump, tell the user beforehand: "Click continue to jump to XYZville".
3) Give a choice at the beginning which "chapter" to jump to instead of just displaying the chapters and then playing them in order.
You could write that it's recommended to do them in the given order, but if someone wants to learn about a specific thing, they can then do so.
Comments about the Airport tutorial:
1) For the order to the second airport, the tutorial mentions that you should not click on the hangar tile. It should explain that for the first order instead.
2) When the user is prompted to look at the station details, he is likely to click on the 2nd airport, which the plane has not yet visited at that time (except the user is suuuuuuuuuuper slow
). Per default settings (IIRC) there will be NO pax/mail piling up and no rating before the plane arrives there. This should be mentioned in the tutorial, or new users might be confused ("WHERE are the waiting passengers, WHERE is the rating? Am I looking in the wrong place?").
3) In the step "We are going to try to build an airport near this town. Please click on the highlighted buttons, starting on the main toolbar.", it only starts to blink once you've pressed "continue", which is inconsistent to other steps. Also, if you already click on the aircraft button before clicking continue (let's assume someone plays this who already knows where the airport button is), the tutorial gets broken. It will highlight the airport button once you click continue, but if you click the airport button then, the tutorial does not go on.
This is all for now. Hope it helps.
