Say you want to have the player choose if they want to form and alliance with computer player AI2. If they select YES, the game will branch to a new scenario with AI2 as an ally (called ai2buddy). If they select No, then the game continues with AI2 as an enemy. And if they don't select anything, after 8 seconds, the scenario will tell the player that the option of Alliance has been withdrawn. How do you do this you say? Like this: [AllianceWithdrawn] You waited too long. Mr Evil thinks that you're mocking him! He withdraws his offer of alliance, and warns you to prepare for battle!
