While THQ is going through an auction today to decide what happens with its various assets, one of those asset partners says that it is not part of the deal. Filing a formal complaint with the U.S. Bankruptcy Court of Delaware, South Park Digital Studios said that South Park: The Stick of Truth cannot be sold off to a new owner without the studio's approval, because of stipulations in the contract it signed with THQ.
That game is being developed by Obsidian Entertainment, but was to be published by THQ. South Park also says that it has the rights to buy the game back itself for the amount of money THQ has invested in the game, and that THQ still owes it $2,275,000.
In a response to the complaint, THQ told the court that it is working to resolve the issue with South Park Studios, but that certain rights can be sold without any approval. It also says that it does not owe the studio any money. You can read South Park's complaint here (PDF), and THQ's response here (PDF). We'll have more details on the THQ auction results when they become available.
