Good timing indeed, for this topic to come along
Up until last week - I'd have said (and, have been saying for the last year or two) that getting the platinum for the PS3 RPG
Cross Edge would be it.
btw - I defy *
anyone* to get THAT True End w/o using a guide...I say that it can't be done!
Now, however - my new answer would have to be getting the (21st NA!) platinum trophy for the PS3 SRPG
Tears to Tiara 2: Heir of the Overlord Seriously.
Goddam!
Playing through, completing, & beating the 50-floor
Bonus Dungeon was more time-consuming & difficult than *entire* games (Like Last Rebellion) to platinum
As usually is the case, though - the more frustration, challenge, and learning from your mistakes & defeats (as amusingly humiliating as they can, may, and will be:) and in overcoming & beating seemingly impossible tasks & boss fights...equals the more pleasant & rewarding the victory and sense or feeling of accomplishment if/when you finally do it
I dunno, kash - does weeks/months of wooing & luring you away from G*FAQs to get your ass here count?!
