[quote name='Krymner']I'm here now to class things up.
Beat ME1 with my renegade FemShep. I played the entire game with Garrus on my team and it didn't award me the trophy! WTH is that shit? It gave me the one for Tali, but not for Garrus. Racist game is racist.[/QUOTE]
No those achievements have always been a pain in the ass and it looks like they couldn't fix them for PS3. Basically you have to do nothing but the main story when you hit the Citadel, get Tali, and then decide who's trophies you're getting and then start doing every side quest in the game, including the ones on the Citadel. Basically meet with Anderson/Udina, go to the mob guy, find and save Tali, then take her to testify talking to no one else except Garrus and Wrex.
If you do everything properly before the point of no return, the trophies should pop sometime when you're on Ilos. I think it'll take a minimum of 3 complete playthroughs done absolutely perfectly to get all of those squad specific trophies to pop so you can get the Platinum. Since you can't get Ashley and Kaiden on the same playthrough. That's why that style achievement was dumped for the next two games.
