Not many changes from the original. If it ain't broke, don't fix it. Roller Coaster Tycoon allows you to be creative in all aspects of the game. A must have if you like strategy games like the SIM lineup. Gameplay is great until you get to where you have to build coasters to their specifications within their alotted time and money.
Graphics are good except for the people.
They have big heads and little bodies. Mostly 3D based things. Lots of color options for coasters, food stands and other things like that. Sound is pretty good. You can hear the people scream on Loop the Loops and on big hills.
