Ken McKown writes: I have always been a big fan of what the guys at Klei produce. The Shank series harks back to the glory days of 2D action games with a mix of gorgeous visual fidelity thrown in. With Mark of the Ninja, they keep their trademark visual style, but have changed up the gameplay substantially. Instead of focusing on straight-ahead action, the game instead turns its attention to stealth. Now, normally I am not a fan of trial-and-error mechanics. I find them tedious, but Mark of the Ninja made it interesting enough to keep me playing with minimal frustration. When I died, I knew why, and that makes all the difference sometimes.
