RollerCoasterBuilder v. Planet Coaster

In 2016, the game developers TechEruo (who created RollerCoasterBuilder) sued Frontier Developments (who created Planet Coaster) for accusing that Planet Coaster is a ripoff of RollerCoasterBuilder.

The Results
Planet Coaster won the case and due to a bet, the Planet Coaster logo was added as scenery to later patches of IX.I and all copies of IX.II.
