The graphic was bolstered. While you still have the same top isometric view, which is not necessarily bad, but GNP. the movements of a roller coaster train have increased by almost twice whereby the train runs much smoother.
And the enscheidenste point when choosing between RCT1 and RCT2 is that RCT1 hardly playable on XP PC's. Supposedly works RCT1 with the add-on "Loopy Landscapes", which does not apply in my case. The situation is similar with patches from the Internet. For me, not a success.
So if you dispense with the lousy 3D implementation and would rather play the altbewerten predecessor, I recommend RCT2.

And who gets excited about the start screen, I can not understand for the life.
