In the last 10 years of gaming, I have certain gone out of my way to get Platinum trophies in games, yet I find these days if the requirements demand collecting an excessive amount of collectables or having to re-play a game multiple times then I usually don't bother any more. I don't tend to look at them on my initial playthrough anyway, but then upon beating the game I might take a peak and see if the games trophies aren't to much on a demand.
I do have to admit, they do have a pull on what I play still even now, I find it slightly less appealing to go back to a game system without trophies than with... like having trophies gives the game some sort of Authentication - Silly I know. I still haven't touch Shenmue II on my PS4 due to being dissatisfied with d3t work on the port, so while I have a Platinum for Shenmue 1, 2 remains at 0% as I still experience that game on the 360 with the Xbox version.
