You can judge the quality of each Dark Souls game by how they handle Mimics.>DaS1
Mimics are used subtly and effectively, they are rare enough to get fooled by and make you scared of them. Best mimics, best game. >DaS2
Gimmick non-enemy mimics that are completely different from DaS1 "just2bDifferent" and are easy to avoid by simply rolling away at a 45 degree angle as soon as you open them. Worst mimics, worst game.>DaS3
Mimics are the DaS1 style again and even add another ground type mimic that crawls on all fours but is ultimately the same, they are over-used and just become an expected encounter that poses no threat or surprise. Stale mimics, stale (but still good) game.
