Cole went through a lot in 
inFamous so it's a little weird to see him a little less dark in the 
Game Informer cover for 
inFamous 2. The art director, 
Matthias Lorenz said they wanted a more grittiness and street without the grumpiness. 
If I went through what Cole went through, I would think I would go the opposite direction. Without going further into the spoiler territory, although the game's been out a while so it might not matter anyways, Cole's adventure in the first game put him through a wide range of emotions that would break down many ordinary folks. 
I'm still looking forward to the second game though as I had a ton of fun with the first one after unlocking the second island.
