Clifford Peters is 19 years old and has recently graduated from high school. A few years ago, Clifford decided to make his own web site. He learned about HTML and started to hand code his own web site. Later, he rewrote his web site after learning about XHTML and CSS. Later, after getting bored with making a web site, Clifford decided that he would instead make a computer game. He tried a bunch of different game engines but did not like using them very much. Clifford then found out about Unity, and after using it for a few weeks, he realized that he liked it because it was easy to use. He liked it so much that he went and bought it, and now he often spends hours a day programming with Unity and developing games.
