The makers of Star Citizen - Cloud Imperium Games and Roberts Space Industries - are being sued by Crytek over misuse of CryEngine.
Cloud Imperium Games has dismissed - in a statement on Polygon - the claims as "meritless" and said it will "defend vigorously" against them, but they may prove hard to wash away.
It boils down to what was agreed upon in a General Licensing Agreement between the two parties in 2012, back before nearly 2 million people pledged a combined $174m towards development of the game.
"Section 2.1.2 of the GLA contained a promise by Defendants to use CryEngine for the development of only one video game," said the court documents.
Crytek seeks damages as well as a permanent injunction to prevent CIG "from continuing to possess or use the Copyrighted Work", which sounds like it could be messy.
