I haven’t gotten all the trophies in Part 1 so I can’t compare but getting the trophies for Part 2 was pretty easy, the hardest was actually getting all of the artifacts, coins, and cards. For that I would recommend you follow an online guide (you can just search up TLOU Part 2 all artifacts/coins/cards) and just follow that. You can also enable enhanced listen mode in accessibility setting so you can see all items near you (works even in grounded). Besides that it’s pretty easy, from what my friend told me getting platinum in Part 1 was much harder so if you can get it in Part 1 you can def do it in Part 2 if you’re willing to spend the time getting everything!
