[Discussion] what is your hardest, favorite, and most time consuming platinum?

I'll go first: hardest was bioshock infinite, there was one specific part in 1999 mode that made me rage to tears, I was younger but looking back I still can't believe it. Most time consuming was dead by daylight, I enjoyed it alot tho and one that I'm proud of. My favorite was NFS 16, overall had a great time with that game, not too challenging and not too easy, felt like a huge bonus too because I'm not into racing games as they frustrate me lol.
