Well, that seems like a bit of work to get the last 30% of the trophies.
I'm in a similar situation for GT5. I've got 70% of the trophies, but some of them will probably take hundreds of hours to get still, like reach A-Spec level 40, B-Spec Level 40 and win everything in gold.
Oh well, I've already got the platinum for Dante's Inferno. If anyone is looking for an easy platinum, DI is your pick.
