Put about 10-12 hours over the past week getting all trophies myself(I only played the core mission once at launch, so practically started from scratch again this week to prep for TPP).
All I still have left is getting S-ranks on Hard for 100% complete on the title screen(~84% currently with all trophies), but I won't bother since it seems doing that transfers nothing. Earning them on normal was pretty fun though, despite a few initial (slightly frustrating) runs to get accustomed to the stealth and avoiding AI quirks, but my opinion really turned around on the game once I learned the map and felt comfortable dealing with the AI.
Very skill dependant, it took me about 3 hours, but you can probably burn through them in an hour and a half.
Cool thanks. UPS doesn't deliver until the late vEvening so I'm gonna see if I can at least get Hideo.
