One of the articles in this volume, “Game Object Component Sys-
tem,” describes an alternative to a more traditional object-oriented model. Al-
though this implementation may be a bit complex, more and more commercial
games are trending toward game object models that use composition (“has-a”) in-
stead of strict “is-a” relationships.
