Ew wait, just because "everyone" loves the game so far i have to love it too? Sorry but there is nothing wrong with having a different opinion. Why are you so angry with me not getting into Planet Coasters Art Style?!
If you are old enough to be my granddad than i am very concerned about your way of handling others opinions. Once again we are not talking about facts we are talking about taste and there is no right and wrong granny[redface]
I'll weigh in on all of this. I definitely respect your opinion to prefer a different art style than they have, there is nothing at all wrong with that.
I will, however, disagree with that opinion and give my thoughts on the matter. I am actually a huge supporter of them leaning towards the cartoony art style. I believe that for a game of this style, the art style they have chosen for it gives it a very polished look and reminds me very much of Cities:Skylines in comparison to Cities XL in it's respective genre. The more realistic look is very hard to pull off correctly, and can very easily result in things looking very awkward such as it does with Cities XL, whereas a cartoony look is a much safer bet, and makes everything look very polished such as how Cities:Skylines does.
Last, it has been shown by many games that a cartoon-esque art style is much more likely to graphically last through the years than a realistic art style. Realistic art styles are incredibly dependant on the technology around at any given time, and when new technology comes out that art style immediately looks dated as future games can look more realistic. A prime example of all of this is World of Warcraft. It took a very cartoony art style and as a result, with only minor tweaks to graphics through the years, has held up immensely well well over a decade past it's release. Yeah, it looks relatively dated now, but immensely less dated than any other game from around 2004.
I think they have done a phenomenal job with balancing the cartoony look with the expectation of detailed graphics of this day and age, and I think it's specific art style will be one of it's selling features to a large portion of the population.
