Probably is trolling but the reason there is no tutorial on MMO development is because if one has to ask how to do it then it probably means they better not try.
Trying to give someone information as to how to make something when they don’t have a clue about the first step is like handing a child a blueprint of an atomic bomb and expecting it built without catastrophic failure.
I worked with Bigworlds Indie for a couple years the tutorial guide to get started is 40 pages long.
the additional reading on how to set up the Linux server and get the cluster functional is 55 pages long. The initial client side programming guide is 118 pages long. the documentation of the server side programming is 183 pages long.
I don’t feel like typing it all but the same principle holds true on any MMO development. Half the people that bought the engine had no clue how to even run the client so as you can guess the developers got frustrated and pulled the engine off the indie market. I don’t blame them one bit.
just saying.
