"Branches of Power lets you play all three branches of government, collectively charged with a critical goal: to build new laws! As President, choose issues you think are important and rally the people around them. As a legislator, craft bills around your constituents' values. As a Justice, uphold the law or strike down unconstitutional legislation. Only through using all three branches cooperatively can you construct towering laws upon the issue foundations that dot the landscape."
