A simple question are there any sandbox games other than the GTA,SR And TES series that allow cheats/console commands?
My answer largely depends on what you would define as open world and what you would define as a cheat. Most popular games when played on PC will have a small community that develops programs that assist in cheating but seeking these out is a dangerous affair (various iterations of malware will often be packaged as "trainers"). And a great many pc games have access to a developer console that can generally be used for cheating. Actual built in cheat codes are largely a thing of the past however.
For example, Two Worlds has access to cheats via a developer console while a game like Diablo 2 has access to a wide variety of third party programs that can be used to modify your character outside of the game.
