Discussion: what makes you platinum trophy a game?

I would love to turn this blog into a discussion area although I know I have a small reader base right now. So I thought we could get the ball rolling by asking about Platinum Trophies on Playstation. I want to know what makes you decide to put the time and effort into earning that shiny trophy and extra PSN level points. Is it because you're an avid trophy hunter? Is it because you loved the game? Is it because you're competing with a friend? And what games have you Platinum-ed?

Let me know and let's talk!

My answer:

I've gotten the platinum trophy for two games: Persona 4 Golden and Gravity Rush, both on Vita. Doing these trophies on Vita was an awesome way to keep playing these two games as I could just do it on the way to work. Once I had finished both of these games, I didn't want to stop playing yet, so I decided I may as well get the Platinum Trophy and use it as my excuse to keep playing! Since then, I keep a general rule that if I love a game so much that I know I'm going to go back to it multiple times or keep playing, I go for the Platinum. It's challenging and let's me see a good majority of what my favourite games have to offer. :)
