* AluminumChristmasTrees: The demon {{Baphomet}} looks like a floating human head, despite his traditional depiction [[https://en.wikipedia.org/wiki/File:Baphomet.png as a goat-headed humanoid]]. However, this tradition only started in the middle of the '''19th''' century! Since inquisition accusing Knight Templars of collaborating with "Baphomet" actually meant UsefulNotes/TheProphetMuhammad, it makes sense for him to look human in the 15th century.
* ObviousBeta: While Creator/MicroProse released a series of patches, this was back when update disks had to be purchased and mailed. Even then, several of the following bugs and quirks were never fixed:
** Every time you save a game, a new file is created. It's easy to get lost in them, and disk space was an issue back then. Furthermore, while you could have as many saves as you wanted, the menu would only show the first 8 saves on the disk, which were not in any particular order. If your latest save fell beyond this number, one had to delete among these 8 saves until your latest save scrolled up.
** The physician could not be employed in early versions. You would be always told you could not afford the treatment, even if you had enough money to buy the entire town.
** Saving a game between battles in a series (Satanic village, Sabbath...) may result in what manual describes as "mixture of you present and past". In other words: your party has fought, lost some HP, spent some potions and DF, weapons and armor are damaged, and you have to start from the very first group of enemies.
** Even worse, defeating devil-worshipers affects your reputation. Thus after loading a game you may get [[LevelScaling significantly tougher enemies]]. Normally you should have met them only at the next Sabbath-crashing.
** At least one of the mine quests is unwinnable. Instead of the final boss you get a huge empty hall without exits.
** Sometimes going up or down a level in a dungeon will instead get you stuck into solid rock. Unless you can solve the mission by winning a key encounter with the rest of your party, the only way out is a reset.
** At least one puzzle must be answered with a blatantly incorrect answer, and that is one that permanently decreases your stats if you get it "wrong". The cluebook even handwaves it by stating that such puzzles follow "a line of dwarf reasoning too arcane for human minds to follow".
** Sooner or later your characters start changing colours. Sometimes animation sprites get mixed and characters start walking backwards.
** Pre-generated characters have weapons and armor that suits their former professions. Clerics and alchemist that you generate are naked.
** Game crashes for no apparent reason every now and then. The patches did reduce the frequency.
** In many instances where you can acquire alchemical formulas, you have no say over ''who'' on your team will actually learn the recipe, leaving you with a one-in-four chance of your dedicated chemist learning it.
* QuicksandBox: The game's "Main Quest" is actually optional. You could spend a long time playing before even encountering the first "plot hook", and nothing compels you to take it. In fact, even if you finish the main quest, you're free to play for as long as you like.
* SuspiciouslySimilarSong: The hamlet (village) song is suspiciously similar to [[https://www.youtube.com/watch?v=7titCKFVIDQ "Glogauer Liederbuch, Part I: No. 113. Der ratten schwanz: Der Rattenschwanz"]], while the grove song is a variation of [[https://www.youtube.com/watch?v=W5_ECf8INOo "Sumer is icumen in"]].
