Simon the Sorcerer: 25th Anniversary Edition

There are some things that kids just shouldn't have to put up with. Being transported to some weird dimension full of goblins, dwarves, swamplings, stupid wizards and sleeping giants is definitely one of them.
After escaping a "welcoming party", Simon discovers that he has been brought on a quest to rescue the wizard Calypso from the evil sorcerer Sordid.
