First Person Editing

First Person Editing occurs when a player can edit the world geometry from a first-person point of view. A game which features First Person Editing as a core mechanic could be termed a First Person Editor, or FPE. Earliest examples of FPEs are Avoyd and Cube, followed by Infiniminer, Minecraft and many voxel games. The world editing properties should extend to the entire game environment, and optionally to avatars. A good test to identify an FPE is if players can write in-game by carving or building.
