Which should I buy

never played Dishonored or any Infamous game

I wouldn't start out with Second Son if you want to get into Infamous.

I never played any of the Infamous games and starting out a series with something like the fourth sequal is a shit way to go.

Dishonoured is fucking awesome, personally. And it's the definitive addition too. That includes all the DLC. Dishonoured is one of those games you'll either just fall in love with, or you'll just drop because it doesn't click. So it's either really worth the price, or potentially not and just a risk instead.

But if it were me, I'd pick Dishonored. Very few games these days do steampunk and lovecraftian elements.

I don't really care about the plot, gameplay and replayability is what I'm looking for here

Dishonored without a doubt.

Makes me wish I had definitive edition, got it and all the dlc on the 360 though.

Just ordered Dishonored. Thanks for the advice, everyone

Both fun games but you'll probably get more out of Dishonored until you realize how shitty the story and world gets by having fun with the deadly powers.
