This was a problem also on RCT3 sharing park saves. The RCTW developers may think that this will add problems in multiplayer mode if one of your friends didn't downloaded the mods that you are using at your park. Imagine that you are making a new park, and you want to make a medieval themed park, but you can't because this content doesn't exist, but you can learn to make your own or visit the Steam workshop to download new content. Steam has Steam Workshop wich should be very important in this game. A lot of users as me ended with more than 5GB of extra coasters, walls, trees, paths.Ī mod API will make the parks much more customizable and the game life longer. Then it was as simple as export the sketchup project and copy it to the Rct3 game folder. I remember you just needed Google Sketchup and 2 plug-ins for it. One of the things that made RCT3 (Roller Coaster Tycoon 3) being played for years, was the easy to make mods or new fan-made content.
