There are many games on the Internet that allow you to sabotage your competitors. Tycoon Online is not one of them, and will never be. All from the start, the creator of the game, Anders Johansson wanted to create a game that would be as fair as possible, and the possibility to sabotage competitors opens up for cheating. It would for instance be easy for friends to gang up on and crush other players with simultaneous attacks.
Sabotage will never be an option in Tycoon Online. This does in fact make the game more special and different from similar games on the Internet.
