Today on Game History Secrets we talk about secret history behind GTA's Cancelled Rival: This Is Vegas. In development by Surreal Software for the PlayStation 3 (PS3) and Xbox 360, This Is Vegas was an open-world GTA styled game that was ultimately cancelled due to troubles with Unreal Engine 3. The game was originally set to be published by Midway Games, but due to bankruptcy, Midway was forced to sell a majority of its assets to Warner Bros., including This Is Vegas and developer Surreal Software, in 2009. Warner Bros. officially cancelled the project in August 2010.
