In short I felt NO reason to stealth through this game, thus it became another shooter with really bad weapons. Thats what let me down. In Deus Ex I could see a reason to stealth. But in this game...why bother?
People usually play how they want to play. If you enjoy playing stealthy, why not play stealthy? If you don't enjoy playing stealthy, don't play stealthy. I ghosted my way through Dishonored and enjoyed it immensely.
