Half-Life 2 delayed until April 2004 because of source code leak

Oh, I saw what you said... but I think that the big difference between the two are quite significant. Sure, both entail doing something to add to or rewrite game code... but in one you are trying to just modify the game as it is (by creating weapons for yourself, or seeing the map, or whatever) while in the other you are making a whole different world... most hacks just aren't in the same category. The only exception I can think of offhand is those hacks ('cogs') for Jedi Knight (multiplayer) that let you create walls and stuff...
