They're fine action games, but I came into them being sold stealth and they are piss poor stealth games. Being godlike really disencntivzes and trivializes stealth mechanics and makes it so the easiest way through a situation is just gun your way out.
I think my problem with Dishonored is:
-I dislike the find the collectibles to power up thing (hope you like hearing royalty free spooky whispers and screams for most of your exploration)
-The stealth always seemed wonky, and in 2 even moreso; the movement feels less precise and the guard AI felt like it could randomly be either blind or have super human vision
-I honestly do not care for the "whalepunk" setting. The environmental art is gorgeous (same guy who did Half Life 2!) but I can't get into the world, especially when the lore and storytelling is so scattershot (1 introduces a trillion concepts that barely matter, 2 exposits like a fountain for the first hour and then forces you to hear about how unfair it is to Emily that people don't like her because she was a terrible ruler who ignored all of the problems)
-I won't be one of those people who whines about being punished for going lethal, but as someone who will always be as nonlethal as possible on a first playthrough, even in 2 the nonlethal options are still dull compared to the lethal ones. It doesn't help how often a guard or NPC will somehow die off screen for no reason.
