Seriously?
I kind of think it's pretty good, but I'm just one and a half hours in. I think the setting is awesome. Hope it doesn't get boring as it goes on.
Dishonored is designed brilliantly, I can totally admit that. The levels are designed in such a way that literally any approach or playstyle is valid, the presentation and aesthetic are unique, the game offers quite a few original ideas and Bethesda, as usual, did a great job with the "world-building". The criticisms I could actually list would be outweighed by the positives and I know pretty much everyone has it in their top 5's.
For some reason, however, I just couldn't get interested. The near-end twist caught me off guard, but I couldn't get invested in the action or the characters. I believe it may come back to Dishonored's moral choice system which a lot of the game is based around, but I thought it was artificial. You're not making the decisions you really want to make, you're trying to play all the way good or evil because the game tells you from the beginning that the story's conclusions depends on your playstyle. It really kneecapped the story for me.
OT - I bought the Hitman HD Collection on the weekend because it was released at a cheap price and I hadn't bought any games in a while. And it includes Blood Money. But as for Silent Assassin and Contracts, they are both so unforgivingly difficult and differently designed that its really, really hard to get into if you're not a "hardcore" gamer or not previously acquainted with the games. The first non-tutorial levels are still kicking my ass and I'm almost regretting the purchase. Blood Money is still delightful, though.
