Perhaps I’m in the minority, but I am always fascinated with the beasts, creatures, and enemy NPCs that developers create for MMORPGs. While there are always very standard critters (such as the feared Giant Spider and completely unique Dragon Boss), many artists and designers whip up original and fascinating fauna for us to ogle (and, you know, fight).
I think that creative beasts is a sign of a well-developed fantasy realm that isn’t trying to ape Earth but is truly attempting to develop a world with its own special feel and ecology. Asheron’s Call was renowned for bucking fantasy tropes with its creatures, and WildStar always pleased me with every alien encounter.
What do you think? Which MMO has the most creative array of beasts, insects, and monsters?
