Cchristina I found 4-5 great tutorials (all about shooting aliens and looting zombies and platforming, but nothing else is there) and I will imitate their game styles before I make mine.
Most tutorials are about zombies and shooting and platforming because those things are easy to code and easy to understand, and most games are like that.
You have these forums to ask about specific questions, and we will try to help, but you have to be specific, you have to put some work into breaking down the mechanics of the game you want to make.
Cchristina Probably something dialogue based (that's what I intend to make)
First thing you have to do is think of what the final game should look like. You can write it down in a piece of paper. It can be something completely original, or easier, something based on an existing game.
Ex: You talk to people, they give you quests, you fetch items.
Or: A FIFA inspired game, a simcity inspired game, etc.
Cchristina with no battles but lots of NPC and dialogue interaction to attain a goal.
What you describe can be partly coded from a shooter or RPG. Interacting with NPCs is no different from interacting with enemies. Data is Data, HEALTH and DMG is just replaced with different scores like "quest ticks" and "relationship bars". These are all tools, the game you make depends on how you use them.
Again, we have no idea what you are thinking, we can only guess. It doesn't seem like YOU know what you want, and this is normal, games start as ideas. You have to sit down and think about the game and the specifics first, this is one of the most important steps.
Cchristina What I am now very anxious about, is that I probably chose the wrong engine, because I only see specific kinds of games.
The engine is a tool. You see "specific kinds of games" for reasons. Small games are easier for indie devs, others make the games they want, which are commonly shooters and RPGs, and you don't see "AAA" highest of quality games in godot because those are expensive, with thousands of people working on them, and companies have usually chosen unreal and to some extent unity for those. Most of the godot users are indie devs and hobbyists, but while there are many games that seem conventional, I have also seen less conventional ones, like:
A 4X strategy game, many puzzle solving games, a pokemon game, and a dialog based RPG with no combat.
If you take a look at channels like StayAtHomeGames, you will see that many godot games are unconventional:

Whatever engine you choose, you WILL have to learn it, and it will take just as much effort. I can tell you as someone who's worked on GameMaker, then BGE, then Unity, and recently Godot. All engines are the same, they have perks and issues, but if you know how to code there is nothing you can't do.
