Dishonored is an unfortunately bad game. There are a lot of great moments and great mechanics in this game, but they are placed in a sea of mediocrity and tedium. The core flaw of this game is the chaos system which the games tell you about at the start. In practice this system seems like a good idea to give incentive to playing a more peaceful but harder route, however, this completely backfires as it moreso just makes the endings that the player gets for playing the more fun method much worse, and even before the ending the dialogue changes and characters are more resentful towards you. All of these would be acceptable if playing peacefully was still fun, but it isn't, going the peaceful route means you will barely use any of the unique mechanics and simply play an extremely bare-bones stealth game where you constantly save scum.

Even if the core flaw of the chaos system wasn't there I believe Dishonored would still only be a slightly above average game carried by the special spells being fun and the world design being cool, because outside of that you have a very uninteresting story that is hard to get invested into and some flat and tedious level design; in fact the levels got so tedious that I quite about 3 missions before the end, I just wasn't having fun anymore and just chose to watch the endings on youtube.

It is truly a shame dishonored ended up this way since it could have been a pretty solid game overall.
