In some examples, terrain associated with at least part of a virtual area of a video game may be sectioned into a plurality of terrain sections. Each of the terrain sections may have one or more associated data collections that store terrain data related to the sections with which they are associated. This may enable multiple different users to simultaneously edit different portions of terrain with the expectation and confidence that their edits will be successfully saved and will not conflict with edits made by other users. In some examples, each terrain section may have multiple different associated data collections, for example associated with different types of terrain editing operations. This may provide further efficiency by allowing multiple different users to check out and acquire locks on different terrain data for the same terrain section at the same time. ## Claims ### Claim 1 A computing system for sectional terrain editing comprising: one or more processors;
