I knew Yahtzee wouldn't love Dishonored but I'm surprised that he liked it as much as he did. He mentioned that the game gets a bit easy towards the end, and I guess that's more up to which skills he picked, but the game is too easy from the start of the second mission if you pick Blink and Dark Vision to upgrade first - your bread and butter abilities. The stealth isn't up to much once you've figured out the guards can't look up and you can instantly be 'up' pretty much anywhere at no cost to your mana after you wait three seconds. The non-lethal assassinations also all feel incredibly token and gimmicky given the narrative, what's required to pull them off, and how easy the regular assassinations are. It's cluttered and as he mentioned it struggles to find a rhythm. A lot of the writing is either a mishandled version of Thief, Half-Life 2 and Bioshock and pretty much anything original to Dishonored is just bad. The world feels empty, there's too much telling and not enough showing, exploration for the sake of learning about the world goes against Corvo as a character, etc.
I really didn't think this game was anything special, it doesn't even come close to Thief or Hitman and I'm surprised people are saying it's the best stealth game in 10+ years, even Thief 3 was better, (and ahem, Blood Money).
