Honestly, it looks fun. Not necessarily true to the SC gameplay, but the style is about right. People forget that Sam Fisher tends to have to really go out of his way to avoid high bodycounts.
Hell, the first one even had an insanely awesome shootout as you protect hostages :p. The games have always been about predatory shanking. This one just seems to do away with the ability to Garrett it up.
That being said, the DRM irks me. So until I can find this for under 30 bucks (with shipping, if applicable), it is a no-grab. Yes, the price of my morals and resolve is about 20 USD :p
