Update 3: Unity co-founder and chief technical officer Joachim Ante has issued a response to Improbable’s blog post, saying that it is “incorrect,” and that live or in-development Unity-based games that use SpatialOS will not be affected by the actions it has taken against Improbable.
“More than a year ago, we told Improbable in person that they were in violation of our Terms of Service or EULA. Six months ago, we informed Improbable about the violation in writing. Recent actions did not come as a surprise to Improbable; in fact, they’ve known about this for many months,” Ante explained.
“Two weeks ago we took the action of turning off Improbable’s Unity Editor license keys. This is a unique case—and not a situation we take lightly—but Improbable left us no choice. This was the only course of action to protect the integrity and value of our technology and Unity developers.”
Unity said that it told Improbable that games using SpatialOS would be unaffected by the deactivation, but that Improbable “misrepresented” the situation in its blog post.
“We are genuinely disappointed that we have been unable to come to an agreement with Improbable, and their improper use continued until we took the action we did,” Ante wrote. “Despite this fact, we can assure developers that they will be able to continue development while we resolve our dispute. We are committed to ensuring that developers will receive support for any outstanding questions or issues as we work through this problem.”
He also clarified the December update to its TOS, saying that it was made to address “ambiguous” language in the terms, and that the Streaming and Cloud Gaming Restrictions are essentially unchanged. The EULA will continue to cover standalone Unity-based servers, or those on cloud-based instances, but if a third party wants to run the Unity runtime in the cloud with their own SDK, “we consider this a platform,” and that’s apparently a problem.
“In these cases, we require the service to be an approved Unity platform partner,” Ante wrote. “These partnerships enable broad and robust platform support so developers can be successful. We enter into these partnerships all the time. This kind of partnership is what we have continuously worked towards with Improbable.”
Unity invited developers using SpatialOS to contact it directly to address any concerns. I’ve reached out to Improbable for more information and will update again if I receive a reply.
Update 2: Bossa Studios now says that, according to Unity, “Worlds Adrift should not be affected by the situation between Improbable and Unity.” The Worlds Adrift servers will thus remain live for now. Bossa also says that “as far as it knows,” Improbable and Unity are working together toward a solution.
Bossa has been informed by Unity that Worlds Adrift should not be affected by the situation between Improbable and Unity. Thus, Worlds Adrift remains live as normal.As far as we know the two companies are working to resolve the situation as quickly as possible.January 10, 2019
Update: “Lazarus is back up,” developer Spilt Milk Studio said in an update on Twitter. The developer has also pledged to keep the servers running until they’re forced down or told to turn them off.
“We’re not quite sure what’s going on—we were told that access to the servers would be revoked by 2:30pm today but it seems that’s not the case. Until either the servers are forced down or we’re told to turn them off, we’ll keep Lazarus live.”
Original story: A change to Unity’s terms of service late last year means that SpatialOS, a cloud platform used in MMOs, can no longer be used with the Unity engine, jeopardising any Unity games that rely on the platform. In-development sci-fi MMO Lazarus has already shut down its servers for the time being.
“All existing SpatialOS games using Unity, including production games and in development games of all developers, are now in breach of Unity’s license terms,” SpatialOS developer Improbable said in an announcement today. Unity clarified the change yesterday, making it a breach of terms to operate or make games using SpatialOS in Unity.
This won’t affect developers using SpatialOS in other engines, such as UE4 and the CryEngine, and Improbable says it’s currently working with other engine creators to see if games affected could transition to an alternative engine.
“Overnight, this is an action by Unity that has immediately done harm to projects across the industry, including those of extremely vulnerable or small scale developers and damaged major projects in development over many years,” the developer says. “Games that have been funded based on the promise of SpatialOS to deliver next-generation multiplayer are now endangered due to their choice of game engine. Live games are now in legal limbo.”
One such game is Bossa Studios’ Worlds Adrift. The creative skyship MMO is built using both SpatialOS and Unity and its fate is uncertain. “Bossa’s main priority is you, our players,” the developer said on Twitter. “Whatever is happening in the background outside of our control, our focus is ensuring players are looked after and your memorable experiences in the game are protected.”
Improbable still believes that a “swift resolution” is possible and lists steps that it plans to take, including helping developers using SpatialOS with Unity to “finish, release and operate their games”. An emergency fund is also being set up to assist developers who will be left in financial difficulty.
Improbable was not informed about the termination of its licenses, a representative told me, and Unity hasn’t informed Improbable about its customer support plans for the developers affected.
I’ve reached out to Unity to get more details.
