Batman: Arkham Knight was the highly anticipated 4th and final installment in the Batman: Arkham series. When it came out, it was widely praised by gamers and Batman fans alike.
Most of this praise was for the console versions, however, since, when the PC version came out, it was plagued with numerous bugs, glitches and issues not present in the console version. This, naturally, led to numerous consumers complaining, giving the game negative reviews on Steam, and refunding the game left and right. The complaints were so large, that Warner Brothers actually had the game pulled from sale on Steam until they could make the game more stable. The PC version would later be re-released on October 28th after patching out many of the performance issues, in addition to including all the previous DLC released for the console versions.
The PC version was heavily hyped by WB and Nvidia, showing videos of the game running at 60 FPS, when the game itself was capped at 30 FPS and saying they were working closely with Nvidia to deliver the best possible experience, a promise which they were unable to deliver on, a case of false advertising.
To rub salt in the wound, in an interview, Warner Brothers apparently knew that the PC version wasn't ready for release for months, yet the game was released anyway.
