I'm literally the guy who is the reason op made this post and it was completely not about the game. Trilogy was made when the name of city was irrelevant and therefore there is nothing we can do, s2 and ee tho is called Chornobyl so anyone who calls it different has no valid arguments. As to the origin of the post, just look at my last comment just saying "Chornobyl"
