The modding community argues they are preserving history. Critics argue they are enabling piracy. The reality is both. The GT4 PKG exists because corporate preservation is a myth. When a game’s licenses expire (car manufacturers, music artists, tire brands), it is often legally easier to abandon the title than to renew them.
