Not really, these games always tormented me by taking just the fighting part of the Pokemon games and bringing them into full 3d on the consoles when what I always wanted was a full pokemon experience. The games on the 3ds are closer to what I always wanted and I cant wait for the switch game to come out. Just imagine if these games where just a part of the switch game so you can visit stadiums around the map.
I think a Pokémon Game like Mario party would be a good idea to revive that part of stadium. In the case of Colosseum, I've always thought of that as being the most like a main line Pokémon game and with the Switch game being set to be Gen 8 I think it will serve the same purpose~
Stadium is what got me into the Pokemon series in the first place, so I'd love to see another entry for the most recent or the next generation of Pokemon.
Not much point in them now, considering the main draw was to see your Pokemon battle in 3D/on the TV, both of which the inevitable Switch game will offer.
Honestly there isn't any point, friend. The new Pokemon RPGs will be playable on a tv, and they'll also be comparable in scope to the handheld titles. They're blending the home console pokemon titles and the handheld ones.
