Considering the price difference between Skylines I and II, I honestly think the difference between the two is very small, but of course there couldn't be much difference in a city game. Besides the price, the graphics quality is "very good," but honestly, what I like most is City Skylines 1, although that's just my opinion.(I don't necessarily consider it a positive point; whether one or the other has more realistic graphics or not, everything can be fixed with mods.) The main difference between the two is the AI ​​system of the bots, but the differences that are said to be grotesque, in my view, aren't that big. The differences boil down to human trafficking (people now choose their paths based on Time, Comfort, Money, Age-based Behavior, Real-Time Events, and Parking)and the economy (Real Input Chain (if the company is a furniture company, you need to supply wood for them to produce), Rent and Space Management, Import of Services, and government subsidies)This causes about a 10-30% difference in the actual gameplay for a casual player.(which is not the price difference) Besides the optimization problems, the more your city grows, the more laggy it becomes (even with low graphics (high graphics are also very poorly optimized)). Another serious gameplay problem: It's practically impossible to go bankrupt in the game. The game sometimes secretly subsidizes some businesses in your city, ruining the experience for people who like challenging management. Furthermore, after 80,000 inhabitants, the game practically goes into automatic mode.There are some bugs related to high customer demand, but some stores constantly give "insufficient customers" warnings, and the store ends up going bankrupt due to AI miscalculations. In addition to other gameplay problems stemming from the game's own internal systems. In short: The new mechanics are good, however:The economy is somewhat broken. Some mechanics are buggy or unrealistic, making it difficult to make sense. It's almost impossible to go bankrupt in this game (the game secretly helps you). Lack of optimization. The price is quite high compared to the first game. The difference between the two is practically only 10-30%, because the AI ​​system for the inhabitants doesn't significantly change the gameplay for a real casual player. Game is 2/10

A solid sequel that expands the scale and complexity in meaningful ways. The simulation feels more ambitious, and city growth is more dynamic, but performance issues and rough edges hold it back. It’s fun to build and experiment, though some features feel unfinished at launch. With updates, it could easily surpass its predecessor. (7.3/10)

Cities Skylines II s'effondre sous le poids de ses ambitions techniques. Là où le premier opus séduisait par sa fluidité, cette suite accumule les problèmes de performance qui paralysent l'expérience. Les ralentissements constants transforment chaque session en épreuve de patience, même sur configurations musclées. Si les systèmes de simulation gagnent en profondeur théorique, leur implémentation chaotique génère des comportements absurdes qui brisent toute immersion. L'interface surchargée noie le joueur sous une masse d'informations mal hiérarchisées. Les bugs récurrents et l'optimisation catastrophique révèlent un lancement prématuré. Paradox livre un city-builder techniquement bancal qui trahit l'héritage de son prédécesseur et frustre plus qu'il ne divertit.
