Kanon

Kanon for the Dreamcast and PlayStation 2 consoles is a port of an adult visual novel Kanon. The console port had adult rating reduced to all ages by removing all the explicit content, but in turn has added new graphical content and full voice-acting.

This all-age re-release for Windows includes updated scenario and removed adult scenes as on the console releases, but doesn't have voice-acting. Smartphone all-ages versions of the game are same as the Windows release in that they too don't have voice-acting but otherwise have updated scenario and removed adult scenes.
