When object-oriented design was first promoted, it advertised that it was easier to modify and extend existing code bases than the more traditional procedural approach. Though this is not true in practice, partially due to the language used by games developers and partially because there is an inherent coupling between objects with respect to their interfaces, it still remains a consideration of anyone who uses it when entering into another programming paradigm. Regardless of their level of expertise, an object-oriented programmer will cite the extensible, encapsulating nature of object-oriented development as a boon when it comes to working on larger projects.
Highly experienced but more objective developers have admitted or even written about how C++ is not highly suited to large scale development, but can be used in it as long as you follow strict guidelines. [LargeScaleC++] But for those that cannot immediately see the benefit of the data-oriented development paradigm with respect to maintenance, and evolutionary development, this chapter covers why it is easier than working with objects.
