I didn't think crysis was all that. It is very pretty graphically but doesn't do anything beyond what FPS games have already done in the past. Hell, I remember an old Quake II mod that did a lot of what Crysis did game play wise, it just wasn't as pretty with a way older physics engine.
The last good FPS I played which I felt had a unique story and feel to it was Bioshock. It had a feel and a game play which I thought was pretty unique as well as the story. I loved the rehashed 50s sci fi feel it gave.
I played Assasins creed at my friends house, and it was cool but it didn't blow my mind. Metroid for the Wii was awesome, but didn't really blow my mind either. I like the interaction it gave with the wii mote was definitely cool.
I find it very hard this day and age to find a game that actually blows me away and that I will want to play over and over again, even 10 years later.
