I recently used a brand of Selenium to script a web based game. [Molybdenum] uses an XML based recordings and runs them as tests. In my case, I played a web based game and recorded some common actions. Like buying hammers and putting money in the vault. I put a [Loop] around my script and now every 10 minutes the game is automatically running my script. Molydbenum runs as a Firefox add-on and is super handy.
