We talk a lot about the importance of game preservation on this forum. Suicide Squad: Kill The Justice League is not a game that needs to be preserved. Not even for one of the final appearances of Kevin Conroy as Batman. It's time to go full Doug Stamper mode and erase this game from existence, to protect the legacy from the (Bat)man. Conroy had so many better scripts to work with in the thirty years he voice Batman/Bruce Wayne in a number of projects. Let this one die. Close the servers, render the game unplayable, decanonize it, and allow it to slowly fade from the public consciousness. There is literally nothing in this game worth preserving. It's objectively a bad game, objectively a bad DC story, objectively an indelible stain on the Arkhamverse as a whole.
WBD, just stop pretending already. Suicide Squad: Kill The Justice League is not "a disappointment". It is the single largest failure from your gaming division. There is no saving it, nothing that can be done to magically turn the ship around and set the game on a trajectory towards even breaking even. Every day that you keep the servers online, every day you allow Rocksteady to continue working on blatantly unwanted content for your complete failure of a product, you are continuing to light money on fire that could better be spent on anything else. No one wants this product. No one will care when you put it out of everyone's misery. It's over. Shut it down. Wipe it from existence. Make this world a little better.
