LOL, every game released for the last 5 -7 years has been "massively overhyped". That's the only way to get noticed these days.

Never the less, Dishonored is a great game that is either too short or overpriced. (Take your pick)
Nope. Neither. I put in 12 or so hours so far: still not done with the first real mission. This is already supposedly past the time when you beat the whole game according to people who call it 'too short'. In all likelyhood, I estimate about 80 hours for me - for one playthrough. And I plan to play it about 2 or 3 more times, soooo... yeah. Am I slow? I guess. I like exploring everything, figuring out the optimal route, planning my steps, collecting everything... Does this describe everyone? No. Is this how I think they intended us to play it? Personally, yes, but thats just an opinion. Short games? God Of War: Chains of Olympus. 5 hours to beat if you do everything, no need to rush. A short game by Arkane? Dark Messiah of Might and Magic. 12 hours to do EVERYTHING, and no real exploration possible, at least not in the way Dishonored does it. Was it a bad game? No, it was a phenomenal, highly underrated game with mechanics the likes of which were really the foundation for, as far as I can see, Deadly Reflex Mod for Oblivion by Skycaptain, without which I refuse to play. Then that system made it into Skyrim, though still lacked DMoMM's kick. Combat was absolutely amazing in that game. ANYWAY. Really not much to say as far as overpriced goes, except 'false', since the amount of content you get is more than worth it - again, IF you dont rush. If you feel like beating the game in 4 hours, like that one video showed, I guess you can do that too, though I find it pointless. But yeah, yeah. 'Always 'I', our opinion is different'. Thats fine with me, but really, you have to see the potential as well. That's all.
