With the varied use of games, the need to measure player's involvement has become prominent. Several studies aimed to quantify users' involvement. However, none of these studies presented a robust framework to measure the player's involvement in games nor considered player types as a factor. In this paper, a framework to quantify automatically the players' involvement in games is presented. This framework consists of three levels and each level includes criteria to evaluate three aspects of 3D games: (1) application level, (2) usage level, and (3) content level. Additionally, the framework's criteria considers player types proposed by Bartle. To validate the results of the framework, player involvement was estimated manually on a case-by-case basis by three experienced evaluators. The manual estimation was then compared with the automatically generated-quantified result produced by the framework. The comparison revealed a significant match.
