- Lack of guidance early game. The game is overwhelming for a player starting in 2020. The amount of hidden information for a new player, most of you who have been playing the game for years and saw the game growing progressively can't really fathom how difficult it can be for a new player to get into the game.
Not to be sarcastic or anything but the game has always been this way. If there is a person who ever found this game easy to get started with I have yet to meet that person. Some of this is unavoidable because of actually complex game mechanics that interact in not easily predictable ways, and I don't think this kind of thing needs to be "fixed" because it isn't broken, but stuff like bins not working and not being able to figure out why dwarves don't do jobs, related to obscure mechanics, probably should be.
In reference to the title of this topic, the goal here is not to debate whether it is possible to succeed or not in DF as a complete beginner, but how to improve the first-time experience of new players.
It is not broken, it is simply non-existent. Does it mean we shouldn't consider adding in-game tutorials? The game has always been this way and that's also one of the reasons why it's always been a niche game. Rimworld has come in the meantime, and it's a pretty good reference for UI and controls.
In Rimworld, there is a tutorial mission that explains all the basics and how to survive your first winter, but still lets you figure out the rest. Tooltips, pop up message, glowing UI/arrows, help understanding the UI better when playing this tutorial mission. The game takes the player hand through the early stages of the game and afterwards, it's gone.
For DF, it might need more than one single tutorial because it's difficult to encompass all areas in one go.
