==== Level creation ====
{{Main|Level design}}

From a time standpoint, the game's first level takes the longest to develop. As level designers and artists use the tools for level building, they request features and changes to the in-house tools that allow for quicker and higher-quality development. Newly introduced features may cause old levels to become obsolete, so the levels developed early on may be repeatedly developed and discarded. Because of the dynamic environment of game development, the design of early levels may also change over time. It is not uncommon to spend upwards of twelve months on one level of a game developed over the course of three years. Later levels can be developed much more quickly as the feature set is more complete and the game vision is clearer and more stable.
