The biggest bitches in terms of single plater were some of the glitchy trophies such as the last two heists. For some reason, the game wouldn't let me but until the last mission the trophy popped up. The online trophies were a bigger bitch because they basically require two people like Rally Driver or Full Refund. But I finally did it! I not only just beat GTA 5, even 100% the single player, but I got the platinum. Took me nearly 2 months, but I got it!
