Sure. I'll ask the most important one right at the start. How many playthroughs does it take to get platinum?

2 i believe.  i forget if hard mode is unlocked with the first play though or not but i know you have to play the game once good and again evil as i remember it.

 For Second Son, just two. One good, one evil (make sure you play at least one on hard), and then clean up any missing trophies during the post story free roam.

First Light, just one playthrough with trophy clean up in post story free roam.

I liked those parts unless had a cat on my lap who got annoyed by me turning the controller and shaking it like a spray can.

I have a question for folks.

When you play the first time through do you go "Good" or "Evil"?

I always do good first and evil second, feel less guilty that way.

I usually straddle the line based on my own feelings toward the situation. However, I'm pretty sure infamous was always a little less convoluted though, so I first went good when I p[layed the original. THe alternatives were like, crazy bad guy stuff.

I've already got the plat. trophies for both games. Second son will take 25 hours and First light between 10 and 15 hours to get the plat. trophy. I enjoyed both games and the "Hard" difficulty was pretty easy for me on Second Son.

I always do the "Good" playthrough when I play an Infamous game for the first time (and any game that have a similar karma system).  I just think is the "correct" way to play a game.

Likewise, and also because it generally provides a better experience. A lot of games that give you moral choices seem to put most of their effort into the good storyline, while the evil storyline is an afterthought that only exists so they can say, "OMG U HAS CHOICES!"

In the game though did find evil bit cathartic to not worry about collateral damage.  "Take that guy with an acoustic guitar!"
