Primal Darkness has been home to me for about 2 years. I have played about 3 other muds in that time, including merentha.
I feel that Primal Darkness is a good mud right now and will be one of the premiere muds out there once we get expanded.
The player base is good, areas for killing is getting better. Balance has been ongoing for about a month and is getting up there. Race selection is huge, along with places to explore, and things to do suck as quests and deeds.
There are fun storylines and fun people to play with, and was one of the more friendly muds I had found, which is why I stayed there.
I hope you all at least try out this mud just for variety!!
