RollerCoasterBuilder v. Efteling Tycoon

In 2008, shortly after Efteling Tycoon got released into Europe, developers TechEruo, who created RollerCoaster Builder sued the European developer Dartmoor Softworks and HexArts Entertainment and publisher Atari Benelux, who made Efteling Tycoon for accusing Efteling Tycoon to ripoff the famous video game RollerCoasterBuilder.

Results
Efteling had no relation to RCB, they were forced to include the Pegasus Wooden Coaster in the next expansion pack, and after that coaster closed, due to the bet, they also had to add Python and had to have a 15-year-deal.
