This is probably really dumb but I've just started playing PGR3 and have managed to beat the London race on hardcore and the speed camera on hardcore but I still haven't earn't any trophies? This is getting boring I only have 1 racing event and 1 speed camera event to play on, I can't open the Las Vegas track as it says I need a trophy. How on earth do you earn a trophy. I've earn't quite a few medals but the trophies seem elusive. I don't even know how to go about winning one . Anyone please for a newbie ?
