Roller Coaster Creator Express is a nice roller coaster game in which you need to design a track in such a way that you grab all the stars along the route. Roller coaster tracks don’t need to be simple: the more complicated, the better; however, there is one constraint: you have limited funds and the roller coaster rail segments are expensive. Especially the special ones like the looping segments, twisters and accelerators.
The game developers picked unity engine to develop the games with. As a result, the game is really nice, but it’s also very resource intensive. This is why it’s better to play it on a computer.
