well i got a few games that i got some "adictional" trophys for collect...
the games are: uncharted 2, nfs hot pursuit, marfia 2 and Red dead rendemption...
so my question is...
do i have to get all the extra trophys and then i got the plat one? or if i get only the main trophys the plat will pop-up?

cuz i collect all trophys on uncharted 2 (main history) and the plat one dont pop-up...

DLC is not required to obtain platinums.

All the trophy's I'm afraid but not extras like DLC.
unless one of those games requires you to do something other than getting all the trophys to get a platinum.

if its not required, why i dont got my plat on uncharted 2?

You need all of the trophies up to Buddy System. If that is done and no platinum, then it may be glitched.
