Oh, sad day, apparently Burnout: Paradise Trophies are not retroactive, testing shows this and this is what Criterion has to say:
Burnout Paradise saves are locked to your profile. We had hoped to use this to retroactively award trophies, but we discovered during testing that this is not possible. You will therefore require a fresh game-save to receive trophies in Burnout Paradise. If you’re familiar with PS3 trophies already, you’ll recognise that this works in the same way as all other games that have added trophy support post-release.
There are 50 regular Trophies attainable on the original disc game, there’s the Platinum Trophy, 6 Trophies in the Codename: Cagney Update and 7 in the Bikes Update. These Updates are NOT required to obtain the Platinum Trophy!
Oh yeah, it’s also out on the PSN today for $29.99!
