serious.
but of course everything is "gamified" , you are awarded more points depending of various parameters (how many pkmn, if they were interacting, special events, other than them being in focus) and you have also (or at least you had in the original, but you cna see traces of this in the trailer) way to interact with pkmn, to get a reaction, make them come closer, or initiate strange chains of events to unlock events like a legendary pkn popping out or a new course opening up.
it was surprisingly addicting but it's a game for a specific kind of gamer, since most of the drive from playing it comes from getting the biggest score and the best photos, and it's not an heavely story focused game like kid loves these days
This doesn't exactly look cutting edge but even then, it looks miles ahead of the shovelware quality graphics in Sword and Shield.
looks great enough..the pkmn style doesn't really need raw power to be pleasant to look at, you just need color, shine and not see edges in the models, which at this point could be achieved on any system really
