In the suit, Take-Two claims the CTA's unexplained removal of the ads violates its free speech and contractual rights. Reuters reports the company is seeking a settlement of at least $300,000 along with the reinstatement of the materials.

"The CTA has refused to discuss with us its outrageous decision to pull advertising," Take-Two told GameSpot, "while running ads for other forms of popular entertainment with similar content, including mature-themed TV shows and R-rated movies,"

The $300,000 advertising campaign, which included banners on city buses and bus stops, was scheduled to run for six weeks. Within the first week, local news affiliate Fox News questioned the CTA's decision to advertise the controversial game, with the ads removed shortly thereafter. At the time, the CTA said that Take-Two would not be charged for the campaign.

The ads include no overtly violent, sexual or otherwise graphic materials that would traditionally prohibit advertisements from running in public. The situation resembles that of past non-explicit GTA ads that still managed to spark months of controversy.
