Since Speedball 2 is the best Amiga game and the CD32 has the best version of it I'd have to say Speedball 2! Different coloured players to tell player 1 and player 2 apart and CD quality sound are just two of the improvements! I also like the CD32 version of Wing Commander with 256 colour AGA graphics. It also has a WHDLoad loader to install to the hard drive of regular AGA Amigas! ;-)
