Are you saying that the console versions of Quake and Half-Life included map editors? I heard something about Far Cry 2 possibly having a map editor bundled, but I never looked into it. Console gaming has traditionally shyed away from editors, unlike the PC, so games like LBP are actually a pretty big deal and will probably spearhead a new push in console gaming for user-generated content going forward.
David Jaffe made some comments about the game looking mind-blowing a few months ago. He updated his comment recently to say that what we saw on the VGA's was not what he was talking about and that he still stands by his statement. So... we'll see.
