As I said, in order to be granted government funds, Glitch's annual earnings needs to be below a certain amount. If Glitch decided to have GameOverse happen after Digital Circus, they might end up earning TOO much money, and lose their support from the government, since they'd be earning more money than what the government would consider an "indie" company to earn
By having Gaslight District as their next show, they can counterbalance the profits from the Digital Circus movie and its accompanying merch sales. On the surface, it seems like the "Fair" thing to do, but in reality, they're doing it so they can continue siphoning taxpayer money.
