Sorry,
But I have to point this out once again because you still dont understand! Please now, read this closely:
I don't want to keep people from breaking their games by adding or changing newGRF AFTER they started a new game, I want to make sure THEY KNOW they cant change stuff after they started a game BEFORE THIS HAPPENS EVEN THE FIRST TIME, -> So that they don't run into a such frustrating position like I got into where I noticed that my game got evily hard because I just didnt set it up right!
Its a little shool everyone needs to know how powerful and also not so much making happy this system can be like at its current state!

How is that different than generating with the wrong map size, unlucky landscape, wrong climate, wrong year, wrong city, industry density, and probably a few others I forgot now?
In all these cases, you cannot change it after you started.

I, for one, would support a text notice or "help" button somewhere obvious in the newgrf window that has a quick explanation of what newGRFs are, a reference to the "online content" button to download newgrfs, how to add them to the list, an explanation that the newgrfs must be added to the list before a new game is started for them to take effect, and other such relevant data. A first-time-run notice like the mockup posted earlier (although I don't like the glaring red) would work too. This, as mentioned, would help inform new users about the newgrf system. Heck, even a button that links to the relevant wiki page would be helpful.

Most of those have behaviour and consequences that should be obvious when changing the setting - anyone reducing 'industry density' should be able to realise that the game will be harder. All climates are playable under normal conditions, and I would suggest a warning for 'Date < 1950'.
The effects of NewGRFs are much harder to predict, especially the many that don't have a readme. For example, how is a new user supposed to know that UKRS2's (and most other GRF trainsets') purchase and running costs are vastly higher than the default ones? Or that they need a NewGrf vehicle set when using almost any industry grf? Or that multiple industry grfs break each other...except the many ECS ones that don't?
None of these things are explained anywhere, nor can they be inferred from any information available in OpenTTD, so I would support the addition of an in-game 'NewGRF FAQ'-style page. Of course it couldn't cover things specific to individual NewGRFs, but it could at least warn new players about some common pitfalls.
P.S. - I'm not an OpenTTD noob now, and haven't been for several years now, but I do still remember my first try at NewGRFs. I added the 2cc set, thought "Why the **** do all these vehicles cost so much!?", bought a couple, and then went bust within five years...
Also, not that long ago I wrote
this wall-of-text post about NewGRFs, which is entirely
not what I'd want to see in OTTD. It's far too long and tedious.

It's the same way, the Adroid port is a direct port. But you'll probably need a physical keyboard and mouse attached to your device.

I install stuff to my SD card and find OpenTTD under the default place where you find in similar folders the data of other applications, too. So nothing strange:
SD-Card -> Android -> data -> org.openttd.sdl -> files -> .openttd

Get yourself a file system browser on your phone and a text file editor and all config settings are yours to change. E.g. TotalCommander is (also) available for Android.

Please don't double-post. Instead edit your previous posting.
Additionally I have no clue what you are trying to say. So please, at the same time, edit your posting for clarity.

Hello there, guys!
Been a long while since I visited here last, so please let me know if this isn't the right place for my question/request. But since I'm looking for... changing NewGRF? then I guessed this would be the thread.
So, I want to add some new buidings sets to the game. I was looking in this page (
https://wiki.openttd.org/en/Community/NewGRF/) that shows several sets, but things is, how do I know if they add instead of replace? For long time I've been playing with TTRS and Swedish Houses, which work great. I don't want the original buildings to disappear and never show up again, I just want more random variety.
Then please, could you suggest me which sets to install? Also only buildings sets, not replacing stations nor infrastructure and etc. Thanks in advance!

most sets replace everything, however, you can make (or find) a set that simply re-adds the originals.
additionally, you should probably make a new thread instead of hijacking an old thread that is just vaguely related to your question.

What if a new game player make newGRF changes before starting the new game?
Once a scenario or save game is created, it is no longer possible to change setting from outside of the active game. As noted in earlier posts, there is a way to modify the setting from inside an active game, but doing this can and likely will corrupt your game.
If you are starting a brand new game, and not playing a scenario or save game file, then you can make all the changes to setting and NeeGRF parameters as you wish.
