Based on some informal research I did ~10 years ago (i.e. I ready the LGPL as a high school student), the LGPL requires, among other things, an end-user license allowing reverse engineering. The LGPL isn't just "my code is GPL, the rest of the program is whatever"; it puts forth some requirements for the entire finished product that are either impractical (must include source code) or illegal (would violate NDA or other license terms for the console libraries) for console games.
