Well, I'm just gonna compare it to Skyrim then, I guess, though if I had to compare it to another game it would be Bioshock.
rich storyline, [...] interesting characters, real life like feels to it and extremely emotional scenes
Personally I don't think Skyrim really had any of that so that makes Dishonored win in all those categories, I guess? It obviously has nowhere near as much content as Skyrim but it is a pretty open game and every objective you get can be done in multiple ways and pretty much every mission has optional side missions that help you unlock different paths to your goal. You can play through the game as a cold hearted killer or as someone who never kills anyone, even key targets.
The world building in Dishonored is amazing, the setting really cool and it's good for a few playthroughs. I wouldn't ever spent 100$ on a game, but I hope that helps you decide if you would. And I think in the end the best thing about Dishonored is the Gameplay itself.
What I can say though is that it's definitely more than worth the 10$ (20 if you go for the 2 story DLCs, which are awesome too) it costs right now.
Again, I think Dishonored is one of the best games of the last years and most of the things you listed, it does genuinly better than Skyrim (in my opinion, though I wouldn't really give either of those games the attributes you listed, so take that as you will). Basically, Dishonored was made by Arcane Studios and they really know how to do First Person games.
As a side note, the Blink ability is the best thing that happened to First Person games since someone decided to give the protagonist a weapon. You can do amazing things with it and it's super fun to use.
