Creative ideas are the seeds of great games. Unfortunately great games aren't built on great ideas alone. Execution actually counts for much more in making a quality product and, on balance, it's probably better to take a well-worn concept and do it to perfection than to do a mediocre job on a brilliant concept. Unfortunately that was the vibe given off by Replay Studios' and Gamecock's Velvet Assassin, a stealth/action game set in World War II about a female spy who sneaks behind German lines to cripple the Third Reich. Unfortunately this great concept is built around a stealth action/core that feels like a cruder version of the one Thief: The Dark Project pioneered back in 1998.
