Yup in java after trying to make it in C++ we have discovered that C++ wouldn't cut it. So we are moving to java and maybe even C#.
If any one can work with C# or java, or maybe even any other program that you think that could support a sand box program of WoW please post below.
Details-
This program would be almost like WoW model viwer. The only diffrent thing is that you can add land, add npc's create vendors, add trees, bushes, and have a sanbox mode were you can start out fresh.
