"A Gameloft employee, who asked not to be named, said a clause in their contracts allowed for a "reasonable amount" of unpaid overtime."

And another clause most likely allows them to quit with a two weeks notice. Why don't you just quit?

A lot of new employees have either relocation or signing bonuses, that would have to be repaid if they left the company within 1-2 years. Compounding this, the bonus is usually given out pre-tax but has to be repaid post-tax.

So sometimes there really isn't an option but to finish the year(s) or take a big financial hit.
