LoadWB: Glad to hear you're enjoying your CD32. Very under-rated, IMHO. There are quite a few very nice games.
Might I recommend:
Defender or the Crown II
Simon the Sorceror (the 'talkie' version)
James Pond II: Robocod
I have many other game consoles to play (yep, 2 Dreamcast's here too) but I play my CD32 at least once per week.
