my utter lack of skill at playing games, makes the 1st less exciting for me. that said i have managed to collect some 39 game trophies. obviously if i've got the trophy its not too tough to earn it.
i only try for trophies when the 1st lands on a week-end, since its easier. you don't need to get the highest score, you just need to get a score right near the review point. since scores aren't reviewed until Monday, the goal is to get close to the review point without going over.
"jetcity78" has the link the known review point scores on his pet page.
