Worst
I was suprised to see the Mystery Dungeon game. I played it once or twice, and it was not fun at all!!!!! Also, I tried pokepark, and yes, it is brutally easy; I mean, some kids under ten might find the game too easy! Pokemon Battle Revolution was by the biggest dissappointment; you get to pick out a pass and do random battles. The took out the trainer towers, mini games, and free-for-all rentals.
Best
Pokemon snap is fun every once in a while. You actually get to explore the habitat of the Pokemon, and it's very interactive. The other non-handhelds that are engaging are the old Pokemon Stadiums, especially the second. The best games are Colosseum/Xd, it's like the handheld games and the pokemon stadiums games combined. I hope that in the future they make another console game like this, except with more opportunities to capture pokemon, and, of course, more up-to-date graphics.
