In RCTW, there is a mode called Scenario which is similar to Campaign. The only difference is that the developers have set you up in a place with a pre-built park that you can edit with assignments to do. For example: the first scenario is where you must take a successful park higher, so the developers have set you a park with high income and money. From here you can forever edit the park but you must stick to the assignments. Another difference about Scenario Mode is that you have a time limit to complete the scenario. This is usually 12 months / 1 year.
This article is about the game mode. For a list of the scenarios that can be completed in game, see Category:Scenarios.
