I am running the rpg 2, when I run the game it cannot find land.world. I don't have it in rpg 2.7z file. Where can I find the file?

Either you make the land.world yourself. But the smartest way is to download the game again. Beacuse you got a missing file. Your download must have stopped. Or the files/link is corrupted.

I just thought I could install rpg 2 and the source, compile it and test it right out the box. I didn't think I would have to design a world first.

Please check install instructions in the erpg2 post. You need to load world in editor and press build

Thanks I thought that was only if I was world designing.
