Yeah, I thought the same. Of course, I never played the original, so I can't compare the two, but what I did notice was the horrible twitchy aiming, AI that seems to be able to see you (and shoot perfectly) from hundreds of yards away, and the uninspired stealth sections. I think I got to mission 4 before quitting in disgust.

"'Casual games' are something the 'Game Industry' invented to explain away the Wii success instead of actually listening or looking at what Nintendo did. There is no 'casual strategy' from Nintendo. 'Accessible strategy', yes, but ‘casual gamers’ is just the 'Game Industry''s polite way of saying what they feel: 'retarded gamers'."
