All versions require a disk drive.
The Commodore 64 version was reviewed. It's billed as an introductory-level adventure, but veteran gamers should not be put off by the label. Actually, Wishbringer offers several very challenging puzzles, starting at the very beginning of the game when you have to map your way over the mountain leading to the Majick Shoppe. What makes Wishbringer slightly easier than a more advanced Infocom game is that some of the mapping is done for you, the scope of the storyline is not as broad, and the puzzles are slightly less devious. However, this should not be construed to mean that the game is child's play - far from it.
