They are also great, but archers sometimes let me down :) But they are cool, liches and fanatics are good, nothing to say... Goblins are very helpful in the early stages of the game when playing as Fortress, and then they become cannon fodder...
I don't like cyclops: I don't get many of them, and I don't always have a lot.
My medusas are weaker than eye monsters, and they don't have many ranged attacks...
Lizards... well... no comment...
You described almost everyone... But you forgot about Maggots :D, what do you think about their "fireball", for example?
And does anyone relate neutral creatures to this topic?
