For one, I was stunned how good the graphics looked! I expected them to be a bit of a step up from the 3DO version, but I gotta say the DVC is one powerful piece of hardware. The graphics almost look too clean, if that makes any sense. Like pc visuals on a console. Such eye candy!

Another thing that surprised me was the load times. I've seen the CD-i chug along w/other games, and I was expecting this one too be a bit slow (The HBG's review also called this game out for load times) but I gotta say (much to my shock) it is actually a hair quicker than the 3DO game. I was stunned! They still could be better, but all in all I was very pleased.
The music in this game has always been beautiful. Imho, it beats out Burn Cycle for the best soundtrack on CD-i.

My only gripe thus far is that the subtitles default to off (in the 3DO default is on) Hence, I can't watch the long intro w/subtitles.
Overall, I love this game. Besides the above mentioned, it has an easy interface, great voice work, wonderful characters, etc ... I could go on, but you get the idea. Cd-i has a few great graphic adventures, and this one if definitley near the top!
