I didn't find it difficult at all. Expert felt even easier for me than Normal. Once you get the hang of how AI operate and how they react to your different attacks and positions, it becomes a walk in the park.
See? Easy =0)
I used to play games all the time, but now I'm more of a casual gamer. I think Second Son is harder than the first game. (I never actually played Infamous 2...) The aiming just seems like it has to be more precise in this one than it did in the first one. That's really my only problem. I generally suck at shooters anyways.
I'm a little confused right now. Because I've played and beaten the last two Infamous titles (played the 2nd one on expert first time through), I decided to play this one on expert first time through as well.
But I didn't get the expert trophy.
Has this happen to anyone else? And no, this isn't hard. You just need to have strategy.
