Hmm? It sounds to me like there is a lot of generosity- Take Two poaching a lot of engineers, offering them nice bonuses. The employees are the ones winning in this story
One of the people involved said he didn't take the offer because he didn't think he'd get the same benefits. Since the contract stuff was about royalties, it might be that joining take-two meant trading royalties for salary/bonus, and as interest grew in KSP2, that might be a shitty deal.
Those employees can expect precisely nothing once the game is complete, unless coincidentally their new employer has another project they can be immediately put to work on.
At least at Take Two the employees have the possibility of working on other games.
