Let's talk Platinums

[Null]

I always go for Platinum's time permitting.

How many platinums do you have? 23.
How vigorously do you pursue platinum trophies? Always if it's a game I enjoy.
What's a common trophy trope that'll actively dissuade you from chasing the platinum? Depends, I don't mind an item grind but having to replay on certain difficulties turns me off.
What's the hardest/proudest platinum in your collection? Cheating a bit as it's technically a 1000g on my Xbox and not a Plat, but I'll go with Mass Effect 2.
