One of the major problems with the Digimon Franchise is that all the games are different from each other. You finish one, want to play another like it and you just kinda can't.
Digimon world 1 - exploration pet-sim
Digimon world 2 - mystery dungeon esk dungeon crawler with 3v3 turn based combat
Digimon world 3 - traditional RPG with singles style turn based battles
Digimon world 4 - multiplayer focus topdown hack'n'slash
Digimon next order - released 15 years after DW1 but we're back to the exploration pet-sim
Cyber Sleuth & hackers memory - released 15 years after DW2, brings back the 3v3 battles and thankfully drops the digibeetle nonsense
Survive - visual novel + tactics style combat?
