The actual development of the game took five years overall to complete and spanned three platforms: the Nintendo GameCube, the Microsoft Xbox and the Xbox 360. Tilston remarked that, throughout the course of development, the team noticed how the video game industry had evolved as computing and graphics power increased, and how earlier games like "GoldenEye 007" and "Donkey Kong Country" where their development costs were minimal could easily be profitable with a few programmers. Tilston also revealed that the team behind "Perfect Dark Zero" was composed of roughly 25 people for most of the project, which was "ridiculously" small compared to Xbox 360 generation standards where there are 100 or 200 people working on a team. Despite this, "Perfect Dark Zero", from a development cost, made four times its money back.
