Space Engineers is still selling very well and only a crazy person would abandon the game! We just want to give people the chance to modify all aspects of our game and experiment with it while we keep doing what we are doing. As we stated above, this is mostly for giving complete freedom to our modders while we continue the game’s development without any changes (through weekly updates and keeping our development plan as described in our previous blog post).

We can be accused of going open source and abandoning the development of Space Engineers.

If our implementation has flaws, open access to our source code and the visibility of potential flaws will push us to fix these cases faster. Our answer: this is true, but with new multiplayer, the server will have authority and will validate everything sent by clients.

Hackers will have an easier time cheating in multi-player.

We believe that our competitive advantage is in being leaders, not followers. Our answer: if it is so easy to clone our games and development methods, then we probably aren’t doing anything special.

“Competitors” can steal our ideas and algorithms.
