Proto:Might and Magic III (SNES)

Text differences
The copyright screen has different text than in the final game, as does the confirmation when starting a new game.

Interestingly, the copyright was originally listed as 1993 in the prototype and 1994 in the final, though the game itself was not released until early 1995.

Other text differences:
 * The Maze from Hell retains its original name in the prototype, but was renamed to "The Diabolical Maze" in the final game.
 * "Diseased Locust" was shortened to just "Locust" in the final.
