\"Originality\" isn\'t a good enough reason to stay away from typical mythological creatures.
But it occurred to me today, that there\'s another good reason for it which I don\'t recall anyone putting forward before in this forum.
If you\'re fresh off the farm or have never been outside of Hydlaa before, chances are you\'ve never seen a dragon or troll or orc before, if they were hypothetically in the game. However, we\'ve all seen these creatures before countless times in movies, books, and games. We have a very strong sense of how they \'should\' be presented.
However, with clackers, grendols, ulbernaughts, trepors, and so on, new players don\'t have a clue!
Maybe your first encounter is sudden and unexpected. It has this wonderful sense of \'newness\' to it which you wouldn\'t have if it were something normal.
And there\'s talking to people in the plaza about all the creatures you haven\'t seen yet. You have only the words of others to go on. That leaves room for exaggeration and imagination.
And that\'s what I think the real benefit is. Colour, imagination, player interaction, newness, maybe even surprise and wonder. It\'s not just to be different - it\'s to create a better experience for people playing the game.
