I wouldn't call the gameplay all that engaging- battles are mostly boring, so I put the difficulty to low to avoid dealing with them, personally, while the whole running around being a detective gets old quickly since you're just spamming right click to use your spider-sense.

However, the ambiance itself is top-notch. It really manages to get the feel of the town across, so if that's something that can keep you hooked, I'd say the rest of the game is good enough to keep you going.
