Coaster Town was a Sandbox-Economy game where players could build, trade, script, and many other activities with other players online. Unfortunately, the game shut down due to an error in an advanced (gambling) script that supposedly crashed all players' games upon entering that park, and at the same time locked their accounts' start-up world to that park, basically disabling their account. New accounts couldn't be created at the time as the game was in beta, and the developer didn't had time to fix this problem, therefore the game was shut down.
1 attempt is currently being made to revive the game
Edit by Dr Doom: Although the script by PINANOOD did cause the game of players to crash, it was only the games of players who entered the park "Script Testing". I believe the reason why coaster town was shut down was because Mean Dean no longer pays for the server and thus when visiting coaster.town there is an Error Code 522. Proof of Mean Dean not paying for the server is that Mean Dean's second game, Diggerz.io, also has an Error Code 522.
