Tiny Toon Adventures: ACME All-Stars is the second Tiny Toon Adventures-based game released on the Mega Drive/Genesis, released in 1994, and developed and published by Konami. It is also the final Tiny Toons game released by Konami. All Tiny Toons releases after this point were developed by Terraglyph Interactive Studios. This is also the first Tiny Toons game to attract a rating, using Sega's US-only VRC ratings system the game attracted a GA (General Audiences) rating. See the VGG page for more information on this rating system.
