Off the top of my head some of my favorite CD-i games are Burn Cycle, Pac Panic, Apprentice, and Plunderball.
If you don't have any controllers, you may want to track down a genesis to CD-i controller adapter. Official CD-i controllers aren't very good.
Also, some models supported or included a FMV module for video playback. Don't know about the Magnavox 450. If you get one of those, some games have extra content and you could play some of the Dragon's Lair style games for CD-i.
