Pros:

Good voice Acting (Michael Ironside as Sam Fisher always a good thing)
Great flow and story line
Great new moves and stealth abilities
Great new diversional tactics
Great Weapons & Gadgets
Pretty Damn good graphics

Cons:
Too Short!!! (seriously, I beat it in 4 hours)
Over-all, Great game even though it's short. there is replay value as there are multiple paths you can take and then the short side games make it fun too. Thumbs up from me
