Postal 2 Editor

I don't know why people find Postal 2 Editor scorned for being hard. It significantly better than original Unreal Engine 2 editor: Show/Hide mode right top of viewport, Add essential Actor without diving into Actor Class Browser, Asset Search, RMB + WASD to move camera and RMB + Q/E to up/down camera, Actor's function explained by clicking its properties, no need to look script comments or become completely clueless (yes, this simple addition helps a lot). If you want to learn Unreal Engine 2 editor, I Highly recommend start with Postal 2 editor even if you're not a fan of Postal series as it easier to figure for new modder.
