To extend your research by leaps and bounds, find Guest #1 and rename him "E=MC2". Then find guest #2 and rename him "E=MC3". The two will meet and begin brainstorming. Shortly thereafter they will ask to be hired on as the park's research developers. Say "yes" and pour your resources into the think tank. The following year, research and development will have grown by leaps and bounds. You will have all of the latest rides and nearly a billion dollars to spend!
