 Published several months before the release of an upgraded Amiga-specific version of the game, POWERPLAY was essentially a straight Atari ST port. [Source: The Games Machine preview (Issue 9, Aug '88, p14), courtesy of the Amiga Magazine Rack]
 POWERPLAY differs from the Amiga-specific version POWERPLAY (ENHANCED) as follows:
- 16 colour low-res graphics (vs 32 colour low-res graphics in the enhanced version)
- Text only titlescreen and game credits
- No hand-drawn portraits of the 21 game characters in-game
- Less detailed backgrounds on the main game screen and in the challenge sections
- One extra challenge section (but more poorly animated challenge sections overall)
- Less sound
- The inclusion of a question compiler utility, accessible from the main menu after booting, which allows players to generate their own sets of questions for the game (removed from the enhanced version)
- DOS disk format (vs NDOS in the enhanced version)
- Colour manual (vs B&W manual included with the enhanced release)
 In 1988, publisher Arcana offered customers who purchased 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).
