I've heard that its a great map editor.
Lets say if I want to make a map from another game(For example Halo 2), is that possible?

It's not good if you want to make a vehicle orientated map. Even though Farcry: Instincts allowed you to publish maps and play in multiplayer if they have vehicles, F3 doesn't. All vehicles and AI can be added, but you can only have them in your map if you're the only one in it.
