Just want to share a little thing I found on the internet two days ago.
Playerworlds.com
From there, you can download a Program that will allow you to create a SNES style 2D MMORPG Client and Server Program.
You'll need your own host/server to run the game, but you can then send out to your friends or whoever the Client program so they can play in your own little world.
You can also use some resources from RPGMaker 2000; mainly the image resources. You can even make your own character sprites at
Charas-Project.net
There are also plenty of sites for tile sets (which are used to make maps), and you can find a good tutorial of the Playerworlds program at onRPG.com
Have fun!
