 Published 7-8 months after the original release, an enhanced Amiga-specific version of POWERPLAY was released by Arcana because they felt that Amiga owners were no longer satisfied with games ported over from the Atari ST and could presumably capitalise on the superior features of the machine.

 POWERPLAY (ENHANCED) differs from the original Atari ST port of POWERPLAY as follows:
- 32 colour low-res graphics (vs 16 colour low-res graphics of the original release)
- Graphical titlescreen and game credits
- Large hand-drawn portraits of the 21 game characters displayed below the checkered game board that accompany the Greek gods as they take their turns during gameplay
- More detailed backgrounds on the main game screen and in the challenge sections
- More finely animated challenge sections (but one less challenge section than the original release)
- A game over screen featuring an encounter with Zeus, King of the Gods of Mount Olympus, accompanied by sampled speech
- Improved sound
- Withdrawal of the question compiler utility contained in the original release due to difficulties experienced by players in using it to generate their own sets of questions for the game
- NDOS disk format
- B&W manual (vs colour manual included with the original release)
 In 1988, publisher Arcana offered customers who purchased the original release of POWERPLAY a free upgrade to POWERPLAY (ENHANCED) if they returned their game disk. In return, customers received the free upgrade accompanied by a letter personally inviting them to provide feedback on the enhanced Amiga-specific version of the game (see HERE).
