Crusader Kings II

Compared to the third game, it looks like a complete game in terms of content, but unfortunately the interface of the second game is terrible. The only thing the third game can do better than the second game is to simplify the interface. The second game, on the other hand, doesn't even have a proper tutorial. All of this combined unfortunately makes it hard to look at the second game in a positive light because it prolongs the learning process beyond belief. The game doesn't have enough language support, so if English isn't your first language, you won't be able to understand everything. Finally, there's a lot of DLC and without it you can't play the game because the main game is essentially a demo. After you get all the DLCs, you reach the main game.
