If you take a closer look at both discs calatogue numbers, you will see they match. But as they are completely different titles, this can’t happen as Philips Media always gave unique numbers for each titles.
But there is more… Othello® and Mega Maze shares the same number twice.
Othello – Testing Phase 1 uses 8100083 (1993/11/26)
Mega Maze final release uses 8100083 (1993/09/13)
Mega Maze – Testing Phase 1 uses 8100163 (1993/03/04)
Othello® final release uses 8100163 (1993/??/??)
We will assume the final release title as the correct catalogue number.
This is not the first time we saw those kind of errors, look here.
Typo from Philips Media? A change of catalogue number in the middle of the way?
That is not a problem as we saw it and defined how to pass through this issue.
