Die Anstalt (has an English option): rather sweet if odd game in which you play a psychiatrist helping toys overcome trauma. Finishing it made me feel all warm and fuzzy :-)
Edit: Also, a cute game idea:
Bone Wars, 'The Game of Ruthless Paleontology'. Poor Mr. Cope; you just don't recover from a mistake like that. And I know some people here will enjoy the related
illustrations (scroll to near end) of prehistoric beasties. [Edit the second: Looks like that latter link requires paid access, and apparently my work IP is already signed up. I had no idea.]
