I can agree Doaky that it is one of the easiest things..
But for a top quality server you need..
Map maker
NPC Scripter
Quest maker
Someone with over all basic knowledge
prob more but can't think of ne at the top of my head
You see the human brain can only function so much, if you don't break the task down or split the jobs up then you won't produce a top quality server.
But im sure there's a lot of smart people out there that can do it all. But allowing your head to rest some can make it a little funner. And make the quality a little higher.....
