I have not played Hacker's Memory, therefore I am only reviewing the main story of Cyber Sleuth. Great entry in the Digimon series. The mechanics are good, game is fun and the Digimon evolution lines are interesting and are very adaptable. Easy to pick up if you have never played Digimon before. Battle system is a good, classic turn-based system which is clear at providing information as to what Digimon will attack next. Unfortunately, it did become very repetitive at times, and some of the soundtrack lacked variety. Storyline was good, but the pacing was inconsistent, with some chapters feeling very slow while others were much faster. Being a Cyber Sleuth that can travel through networks was a great combination and felt creative.
