Finally finished Infamous: Second Son, at least the story. Went Light/Good Karma. I probably won't replay the game just yet, at least not for a long while.
SPOILERS:
I was pretty disappointed by the end, particularly the final fight with Augustine. After Reggie gets killed and you fight Augustine, I thought that was really cool... but having to fight her again not so long later in almost the exact same way, that was kinda boring. Her whole giant spider rock thing was kinda cool, but that fight felt so slow. I wish I had more shards at the time to upgrade the concrete powers.
I knew the forth power was gonna be concrete considering that's what Delsin was after for the entire game. The concrete powers are pretty cool, especially that boulder dash. It sucks though because I don't feel very inclined to collect more shards to upgrade the concrete abilities.
END SPOILERS:
Overall it was a pretty cool game and the powers were fun, but somehow I feel disappointed. Ah well.
