I must preface this by saying, it's so not my thing. I have no interest on comic books and my enthusiasm for PC games is almost entirely sim-orientated, contemporary and realistic.
However...
This is a beautifully made game. It almost counts as Art. The voice acting, atmosphere and character animations are way beyond almost anything else I have ever played, and it is so well written that it's easy to ignore the story-driven scripted events and contrivances. The music is fantastic and all the creative decisions are really sound, i.e. the relationship of the "core" game to its mini-game subsections, challenges, power-ups and informational media discovered by the player, etc. The combat involves a lot of button-mashing, never optimal on a PC keyboard vs a controller, but the scripting, animation and presentation is so fine that you just have to lean back and chuckle when, thanks to a string of seemingly random mouse inputs, Batsy unleashes martial arts hell on the biggest, ugliest crew of biker dudes since "Mad Max". It's a hoot. Finally, the stealth gameplay is terrific; like the Splinter Cell series it's about gameplay balance, the environment and severely limiting the lethality of the hero's loadout. However, no game, not even Splinter Cell, is so well-tuned in terms of control harmonization, to provide such satisfaction at dispatching a villain by stealth takedown as this.
I still have no interest in comic books. But this game is a masterpiece.
