The first Digimon game I remember playing was Digimon World 4, and the second one was Digimon World: Data Squad. I remember playing as Dorumon in the former game, and not getting that far in the latter game, though I saw my brother get way further into the game than me.
Late reply but I got into Cyber Sleuth recently. Friend of mine kept telling me to get it and it’s great, though I took a break since an Eater was beating my ass.
