Yes, I worked for an RPG game long time ago. Not completely 3D, was isometric view from the top, I made only the models of buildings and stuff like potions, etc. The project was canceled. Theres no money in that work anyway, I do that for free and fun.
More, this ar some pitures from the game that was canceled. All the buildings are made by little pieces of walls like a lego game because when the character walks Through a building some parts has to dissapear. All made in 3D.
