well I think Deus Ex Human Revolution suffered due to it's direction, just like Dishonored may, I mean Stealth games aren't the games for casual market, DE:HR sold around 2.5:3 Million Copies which is a good indication about the no. of hardcoe players, nowadays most of the market are casual players, and that's why some major series is adapting to it, like Resident Evil, Medal of Honor, THQ releasing Homefront, and more and more.
IMO Dishonored need to focus on who they are targeting, if they are targeting Casual player then alot of explosions need to be shown, if hardcoe then deep stealth system and true sand box style maps, I remember seeing quite enough of DE:HR there was the social system demo, the Sarif manufacturing plant demo which was shown with a stealth and action gameplay I think.
But still I believe DE was more pushed towards hardcoe fans, which is a big reason why I love it, playing it as action title didn't feel right, yet at the same time it didn't mount up to 5:7 Millions, I hope at least Dishonored get 5 Millions, and since it got a vibe similar to BioShock and Thief it will probably have alot of support, so who knows.
yet 3 Millions isn't really bad either I think ?!
I am not sure they need to pick one type of gamer over the other, even if those parameters were what summed them up., This game purports that it will leave the options of stealth or all out assault up to the player. Supposed to be all about consequences too, so hopefully that means either playstyle will have its rewards as well as downfalls, storywise.
I like the art direction in this a lot more than Brink as well. The character models were pretty cool for bring, but the rest was kinda "meh" for me.
This game seems to have an air of fantasy, sci-fi and a bit of steam punk. The character models and world both look pretty good.
So long as they can keep it from tearing or lagging their only concern will be if their cause and effect selling point is all its cracked up to be.
