Less demanding. None of it is custom coded like RoF and AoD. Probably 85% of it is a one and done setup. The world, the interior structure like permissions, etc. Once it's done there wont be a lot of upkeep other than content additions, balancing, and bug fixing.
Hmm so MC updates will be less painful as well.
At least its nice to know, that it won't crash and burn horribly just like it happened to old Primordia.
I know, that leaders will play a lot and be creative with stuff, if there are lots of active people in their clans.
Hopefully combined effect of server features and good leadership will keep servers popularity for long time.
It would be funny, if no one joined RoF, Create and AoD for few weeks, as everyone would be playing Primordia ;^)
Edit: Ogarci, its like 2 AM right now for you o.o
Edit: Here you can see playerbase dynamics for whole lobby:

Are there freelancers?
How clan numbers will be balanced with each other?
A clan with crappy leadership will be ugly sight (Gaia in original Primordia). How stuff like this will be dealt?
