Platinum for Fallout 3 GOTY edition ps3?

i have fallout 3 GOTY edition and as some people know, its very glitchy BUT im like 7/8 trophies to go til i get platinum so my question is can i still get a platinum by not completing the addon trophies or do i have to get every single one of them in order to get it (its because the mothership zeta alien addon is the glitchiest glitch addon ive ever came across and its going to bascailly stop me from getting the platinum :/
