This is another rather obvious entry for a feature such as this one. Dishonored is a game with many strengths, from its reactive systems and the resulting emergent gameplay to its excellent world-building to, of course, the amazing stealth gameplay. Another major highlight is the way Dunwall changes in response to what you do throughout the game. Rewarding or punishing players based on how homicidal they are is something stealth games have done quite often, but Dishonored takes it to a whole another level. The more you kill, the more decrepit and plagued by deadly rats the city becomes, which, of course, affects NPCs, environments, and more. Watching an entire city eat itself alive or pull itself out of a horrible situation based on how you are playing the game can be surprisingly powerful.
