1. I got a gold medal in every race, crash course, takedown event, and lap time race in Burnout 3 - Takedown. I probably put a good 150 hours into that game to get all the golds. You should try racing an F1 car at full turbo around a lap, against traffic, with all sort of obstacles and tight turns to beat the gold medal lap time without getting into a single crash or slow-down. Literally, a perfect lap. It will take a hundred tries before you get it right.
2. to find every single boss (mandatory or not) in Demon's/Dark souls and defeat them. Also beating Smough before Ornstein in the Smough/Ornstein boss encounter. Haha, that was fun.
3. Dominating with tmp/knife combo in counter strike to defeat all opposing players using AKs, M4s, Snipe Rifles, and Paras.
Despite all that, I couldn't care less about platinum trophies...
