Infamous 1 and 2 are outstanding. Among the best games to have come out on the PS3. Second son on PS4 was a disappointment.
if they made remasters of 1 and 2 for next gen i would probably buy.
1 and 2 are EASILY worth 2 playthroughs each, as you get different powers based on which karmic route you choose. Only thing I’d caution is that despite “karma choices” it’s not an rpg. You are basically incentivized to be totally good or totally evil so it’s kinda simplistic that way. Which route you choose in 2 affects the story more as well. Those games were definitely made to be played twice. Did not get the same vibe at all in second son
