I was wondering if it would be possible to import an already existing game (i.e. minecraft) and edit it in unity. Is this possible or not?
If you have the unity files (not the build ones), you can open it just as any project. Don’t try to open Minecraft or MassEffect with Unity though.
What about Ultima Online? Most of the files are written in C#. I just want to make a clone for my use but updated with 3d top-down graphics, skills, rescources, etc. I also have a runuo server that has a good amount of C# scripts in it if you are familar with Runuo.
