What they should have done is shared the success of SC with Crytek.
What they should have done is upheld the GLA...and not paid Crytek a penny more than they needed to.
But the question was whether or not CIG could legally fulfil its contractual obligations if it switched to another engine.
For example...the GLA provides CryTek with a right to sue Star Citizen to promote CryEngine. But CIGs move to Lumberard would strip that right away with no compensation. Some might say tough
But the GLA also requires CIG to promote CryEngine via a splashscreen. However, it appears the is clause does not depend on the engine being in use. It simply states CIG has to do something in exchange for the right to use CryEngine. However, if they promote CryEngine as contractually required at a time when they are not using CryEngine, that could possibly be construed as fraud.
In essence, even discounting the question of interpretation over the word "exclusive", do the terms of the GLA ensure that the only way CIG can legally uphold its obligations is to use CryEngine...a de facto exclusivity clause even if there isn't one mentioned specifically?
