The purpose of this study is to examine children's expectations from games and their interaction patterns while playing computer games. 52 children ages from 8 to 14 participated to the study. Children were allowed to play computer games according to their preferences and interact with each other in a social gaming environment. Data were collected by observing children and taking notes to capture their interaction patterns. Also semi-structured interviews were conducted to examine their expectations from computer games that they had played. Results of the study showed that students mostly interact while learning a new game, providing strategy to their peers and promoting their success. Gender has effect on preference and expectations of games.
