So far it doesn't look like a difficult plat but completing all the riddles ( 243 total riddles) is a bit annoying.  You also need to complet all the riddles to get the real ending.  Also, there is a lot of trophies in this game which most of them are gather by completing side missions and the main quests.  I will recommend it if you are willing to pour a considerable amount of hours into it.  I'm talking about 50+ hours easy.  By the way, I'm still working on it. 

Rocket League is an easy plat, half the trophies can be earned in an offline 1v0 match.
Infamous SS and FL are pretty easy, the challenge modes aren't that hard but a bit of practice and you're done.
Bloodbornes a pretty easy plat too especially if you co op all the bosses with a friend, just be aware of the things needed to complete the three endings in one playthroughs.

Bloodborne, game itself is hard but the platinum is very fair to get. No collectibles BS

Wow, nice recommendation list!

Rocket league
Transistor
The order 1886
Strider

Knack can be a grind though since there are some items that are random, though the free app does help a bit

Thanx i will download the knack app on my phone

Platinum in Lego games is easy to get and the game is lots of fun!

Thanx 

Are transistor and strider on plus ??
