1. download from japanese store with japanese account.

2. press O instead of X when the game is running even if the interface menu is from PS4 always remember

3. First option is playing music second option is changing characters. Each different character will give you trophies for playing music

... I did this back in 2014 when I got my PS4

Im asking this serious, is there an advantage for having more trophies? I never check how many i get, i mostly just finish the games every way I can :p

Wtf? O.o

2014

The advantage is that your dick gets longer with every platinum trophy you get. My dick is already huge so I only have 2 plats to round it up nicely.

I haven't noticed any changes myself but yeah their just for bragging rights. :-p

IIRC there was a pretty nice promotion in Media Market in Germany where they gave a discount on a PS4 if you could show you had a large number of trophies. And I think Sony has had a contest where you could use your trophies basically as raffle tickets to get prizes.

A shame for every true trophy hunter...

Besides this:

I haven't heard of any other real life usage for your trophies.
