Put some competition on the web, by making a game called Brickworld, thus starting an advertising war costing Roblox to go out of business. Then strike a marketing campaign in an attempt to drive Blockland out of business. This would result in a failure, until 20 years later where you decide to purchase television commercial times, and then thousands of children join together in a militia against Blockland, thus starting a Cyber-War. The end of this would result in Disney buying out Blockland, and Lego buying out your BrickWorld. You and Eric would then become friends, buy an island in the Galapagos, and retire millionares. While that is happening Lego and Disney are destroying each other in attempt to become the higher entrepreneur with selling their game to children. Concluding that Disney and Lego will someday destroy each other in an attempt to sell their products.
