Congrats! Yeah, after getting my first platinum trophy, I got hooked... That's right, there's no special treatment in achievements for collecting every points, but in the PS3 world, you're rewarded with the delicious Platinum trophy

Not only looks good on the trophy stat (plat/gold/silver/bronze Olympic style) but also boost your leveling up experience points (level up faster with Platinum trophies).
Yeah, most people tend to remember their first platinum. Also, you don't need all of the DLCs to unlock it, just need to collect all of the in game trophies (personally, I don't know why the formula is like that, I mean, why can't they just offer a platinum trophy for just beating the game? :lol
Tekken 6 plat? Wow, impressive... And for those plat Little Big Planets, congrats too, that's one hard platinum (hats off to those with Resistance 2 platinum trophies too, it's almost impossible :lol

I agree that Uncharted and U2 are both enjoyable platinum trophy games, I absolutely love them (CRUSHING mode is a pain though especially Uncharted 1).
