VBGore is a free open source MORPG engine.
It's coded in Visual Basic 6, and is 2D/3D (Kinda like Pokemon graphics)
Its a nice engine to mess around with..Maybe use it to get started in developing.
It's pretty easy to use, and pretty much strait forward.
I used to mess around with it in my spare time.
