Player made content Edit
Creativerse already enables and includes user content like player-made shareable Blueprints (for buildings) in the workshop http://steamcommunity.com/workshop/browse/?appid=280790&actualsort=toprated&browsesort=toprated&p=1 and the special game mode "Adventures".
Adventures are instances of player worlds where sightseeing tours for buildings can be made, and all kinds of player-created quests, jumping/flying parcours, rollercoasters, labyrinths, puzzles of all sorts with spawnable mobs, treasures, checkpoints to search for, disappearing/appearing walls (or floor parts, stairs or platforms), timed devices like lights, doors to be locked with number puzzles, switch-puzzles, quest-like stories to be told and much more like that.
The game also offers several customization options, from the look of player characters to nearly all key settings.
Actual modding Edit
Making Creativerse actually "moddable" is being considered by Playful too - however at a future date.
This is what the official FAQs stated for years until the launch of the game (May 2017):And this is what members of Playful have stated about this topic on the forums:
In November 2016 it was stated that Playful still has to figure out how to avoid certain typical problems that mods can produce before the developers will be able to create a modding API.
Like how to deal with copyright-issues (like when modders use copyright reserved content) and other legal issues, that could damage Playful's reputation as a side-effect if blown up by social media. The game balance is another topic to consider, especially when game-breaking bugs originate from player-mods - like when they aren't updated by their creators anymore (which happens so often after a couple of years) while the main game continues to change.
Playful themselves have clearly stated that they will not be able to offer support for any of the possibly hundreds of mods that could be added to the game after modding will be enabled. As an example: just one month after the workshop was opened for player made Blueprints, over 5000 of these were added, and the count still grows.
A way has to be found to coordinate the official game development with player mods, since Creativerse is still updated ca. every month and sometimes with very large new features, which would force game content modders to update their mods very often. And there are features that Playful plans to implement to Creativerse, some of which are already under way; but what if several amateurish player mods would offer these same features before the official professional development is finished and polished?
Last but not least Playful has to find a way to ensure that player-made content, skins like block textures etc. will not recreate, obviate or preempt the purchasable content offered by Playful that is necessary to finance the game development...
It is already possible to alter Creativerse game data/files; but this can get you sued Edit
Nowadays many people know how to extract graphic files or take a look into Unity files of a game program.
However you are not allowed to use this in any way to alter the game or make the data known on any public platform. If you want to do so, you have to ask Playful as the copyright-holders for their permission beforehand.
