Greeting gamers...
here comes another noob question...
why must we update all of our game after we updated our firmware ?
after i update to firmware 3.73, i must update all of my game.
Why is that ?
and this happen to me last month :
i didn't updated my firmware to the latest update...
i play uncharted till finished and got trophies and stuff.
after a while, i updated my PS3 to the latest firmware and updated my games..
when i play uncharted all of my trophies gone back to 0%
but when i check my saved games, the uncharted saved game that i finish is still there...
Why is this ?

have you sync your trophies to server before updating or playing online?if not,then u need to get those trophies back.
as for game update,do u mean Killzone 3?new patch just released yesterday.
