Batman: Gotham by Gaslight

About

A Batman: Gotham by Gaslight game could've taken fans to the cobblestone streets of 19th-century Gotham, but the project never saw the light of day. A Batman: Gotham by Gaslight game nearly followed the release of 2008's Batman: Arkham Asylum, but the project was sadly canceled before it could see the light of day.
