inexpensive engine solution

[bonabalta]

Hi, I am a graduate student studying game art. I have imported characters into the unreal engine so far, but I am looking for a complete, inexpensive engine solution for making a multiplayer online game. I know some programming but I am trying to avoid learning something like C++. I have heard the blender engine is powerful...but I cannot find any books written on after 2001 so I am wondering if it is out of date. Thanks!
