Dishonored is one of my favourite games of all time. The reactivity alone in that game is utterly insane, and when coupled with incredibly fun stealth mechanics, extremely open level design and amazing art style, I can't help but say "What is there not to love?"

As for similarity to Dark Messiah of Might and Magic - I wouldn't say they're that similar, actually. DM was a lot more focused on combat and had much more linear levels. Combat system was also entirely different, along with stealth mechanics not being nearly as tight. I guess what you're primarily referring to is Arkane creating games which give player a lot of options at any given time - but, generally speaking, I'm kinda fine with that :-P So on ... One hand you don't like these optional features but on other hand you're going to use them in spite of them being optional? Where's the logic in that? I never played Dishonored with objective markers enabled. If it was their "creative vision" to have objective markers, there wouldn't be an option to disable them.

As for seeing trough walls, that power is so entirely unnecessary I never really used it too often anyway - the game has great sound design so you can easily hear dudes trough walls and you should stick to places where you get to see your opponents before they see you anyway, the x-ray vision was kinda unreliable at times.

Generally speaking, before writing something off as "Masochistic", you might want to give it a shot first.

Yeah, it sucks, and is addressed in the DLC. However, I've had a lot more fun doing a ghost run than I've had with a full-out murder run, so I'd not say it's "Robbing player of fun" - more along the lines of silent sneaky types not really needing all that many tools at their disposal. Even with massively widened pacifist arsenal of Knife of Dunwall, I still didn't really use anything, ever.
