Cyber Sleuth and Hacker's Memory are fantastic games. I'd argue that as far as Digimon video games go, they're the absolute best we've got thus far (though I guess we'll have to see if Time Stranger takes its throne!) It's one of my favorite games of all time. The playthrough I did before writing this was my 8th one, and it likely won't be my last. There are some issues with story pacing as a result of it making you stop to do side quests, but that's nothing new, as previous games in the Digimon Story issue did the same. It improves upon previous entries in significant ways, having a much more engaging story and being significantly less of a grind. It shows its limitations a bit, the result of being a decade old handheld title, but I don't think that hurts the overall experience much. I'd absolutely suggest anyone who likes Digimon pick this up, and even say that it could be worth a play for someone who just likes monster collectors and JRPGs in general.
All in all I am a very big fan of Anode Heart. It's been quite some time since I enjoyed a game as much as this one, and I would strongly recommend it to anyone that's a fan of the Digimon World games, or of monster collecting RPGs in general. I've only given a very high level overview here since I think anyone interested should get a chance to experience it for themselves. But if you don't want to take my word for it, the game has a free demo, so go ahead and give it a shot yourself!
