I wouldnt go that far. Skylines 2 has a new game engine. If it wouldnt have turned out to be incredibly slow, it would have been a very successful launch.
And I cant imagine anyone buying Skylines 2 if it used the same engine as Skylines 1. Then it truly would have been no point. The new engine was supposed to make cities more beautiful and more realistic. They just didnt manage to make it fast.
I unfortunately bought the game for 50 dollars on launch day and I have just 3 hours in it. I cant bring myself to play it because of the sluggish feeling.
I didnt know it was a new studio too. Thats a classic mistake.
