A few new ones for me:
Super Mario Galaxy 2 - 23 hours
FFXIII - 55 hours
Rathet: CiT - 11 hours
Can't remember WKC. =/
Also, Trusty Bell is the Japanese name for Eternal Sonata, so you should combine the two entries. How somebody spent 200 hours on that game is beyond me. 0_o
Edit: Just read your latest post.
