Rafaele Cecco's games all have a certain kind of a quality, that make them all feel most at home on the Spectrum and Amstrad for some reason, but I've always thought Exolon to be one of the games that was almost equally good on every 8-bit. The 16-bit versions I never even knew of until I started doing the research for this entry, so it'll be something new to look forward to, at least for me. Exolon also has a certain amount of randomness about it, that makes it impossible to feel completely comfortable about it at any given time, and perhaps for that reason, it has never been one of my favourites, but that hasn't stopped everyone else from liking it.
