What games were better (in your opinion) on the Sega CD / Mega CD?

Obvious choices are Batman Returns or The Terminator, but I also found Pitfall overall better (had 2 or 3 more levels, more cinematics and a smoother OST), and Flink and Mickey Mania to be a bit more appealing. The latter seems a bit more complete and the former profites from the CD audio.

Any other games that came out on top in the CD version?
