I just got my first platinum XD. What was your first platinum trophy?

[Sensei]

My first on PS3 was Tekken 6, 4 years ago.

First on PS Vita was Plants vs Zombies.

First on PS4 was Sound Shapes (or Resogun if you don't want to count Sound Shapes as it was just a mirrored Platinum from PS3 and PSV).
