The newest gameplay trailer shows multiple strategies for the same part of the game.
The Good: First of all, it almost felt like an open-world experience. Sadly, it isn't. However, we see the freedom to choose your strategy I believe Harvey Smith has had a large role in (lead designer for Dishonored, known for titles like Deus Ex, which has a strategic system). Viktor Antonov, the guy who designer City 17 in Half Life 2, is doing a great job with Dishonored's Dunwall. The game is dynamical and the "chain possession" method looked like the one I'm going to use most simply because it was devious and awesome.
The Bad: The game graphics look outdated. The gameplay looks aged. Older gamers will most likely feel pleasant nostalgia, but Dishonored isn't likely to become as popular as Skyrim. And after what happened to Troika, the company of geniuses which made awesome games yet faced bankruptcy, I'm worried for Arkane too. And it still isn't an open-world game.
The Ugly: FOV manipulation was too dry at times, could hurt game dynamics. When falling into water, PC's weapons suddenly disappear, replaced by empty hands. Some holstering animation wouldn't hurt. And I would really appreciate better graphics.
The verdict is - I like what I see, but there's still much to improve. Let's see what comes out in the final product.
Update: Harvey and Raphael are answering questions on Reddit. Got questions - ask them.
