TTD420, Download the Demo First, If you like it and it work on your machine then it is up to you to save up and spend the $25 on the software. Trust me you wont regret it. I got the software for $20 back in Nov 2001 when it just came out as version 1.0, back then I never thought it would become as awesome as it is today. It was the effort of all the Coaster Enthusiasts that knew how to work the program, do the 3D modeling, do the textures, and do the sounds that made NL as awesome as it is today. From a few months from now that game will become more awesome when Shuttle Coaster Support comes, along with 3 or more new track and train styles to come, and of course better models of coaster trains for the icing on the cake. I Also suggest buying it as soon as possible, because I have a feeling when 1.5 comes out the price for NL will go up. NL was the best $20 I spent on anything.
