Sandbox mode or creative mode

Make a mode where on any map, and individual can have all research unlocked, and the ability to do as they please. And unlimited number of vehicles, unlimited everything. Essentially allow for a game mode where there are no restrictions so players can choose to terraform or build whatever they want. Basically a mode where players can more so interact with the map and do whatever they want, rather than focus on the logistical necessities mandated to upkeep full map exploration in the construction of massive facilities.
