I dont know what to think about this game its not bad but i dont like it somehow. mainly the firs con is the fact its coming for the DS (really? Nintendo? WTF!) I would be more happy of news about new pokemon classic on 3ds or Pokemon ranger on 3ds or pokemon mystery dungeon on 3ds.... or Digimon on 3ds.
The DS isn't dead quite yet, I'm pretty sure more people have DS's than 3DS's now, so they're better off killing it slowly instead of just moving on abruptly. And classic pokemon? Like awful Red/Blue? I guess the nostalgia folks will eat that up.
Since Disgaea has gotten me into tactical games, I do think that the mix with Pokemon would make for a fun adventure, so long as they don't limit you to only getting certain pokemon while making you battle the rest but not actually be able to capture them. If you're going to make a game about pokemon, at least include all of the little critters in the game so everyone can use their favorite.
