Partially agree: it shouldn't be a clone, but a game that like MH or Pokémon exploit some borderline obsessive-compulsive mechanism in gamers, pushing them to buy more and more games of the franchise to get more and more items or monsters or else. DS, 3DS, PSP and PSV HW and SW sales seem to show that portables particularly need such games, but a clone wouldn't go very far, it must be something new that in common with MH and Pokémon just have a carefully devised way to exploit such mental mechanisms, and around that devs must build great games to increase the appeal and hide the underlying psychological exploit.
