I remember the days of the gameboy and the N64 as Pkmn Stadium was one of the best games in the entire series, with an in-depth guide to battling for newbies and veterans alike, and an unbelievable amount of usable poke'mon to select from, as well as the ability to use your own gameboy poke'mon to battle in it. When I got Pkmn BR, I was hoping for the same thing to happen; I didn't get it.
It isn't too bad, honestly; you're allowed to send all your poke'mon from your DS games (Diamond, Pearl, Platinum, Heartgold, Soulsilver) to equip to mulitple different trainer personalities, and with the huge amount of poke'mon being over 450 is a pretty big pill to take; lot's of variety. However, the character creator really is pretty limited as you can choose from only 6 character palates, and have to unlock un-alterable costume pieces.
The gameplay is the same as any other poke'mon game, and has been sped up from the last 3D adventures on the Gamecube; faster battles plus even more flashy animations leads to brilliant battles; fighting against other players is a definitive must if you can. The WiFi battles have somewhat good connection, although by the time of this writing it's most likely the online battles have halted.
The huge problem with this game, however, is its lack of substance. You can battle-and only battle, usually in stadiums with the same generic rules of elimination; defeat this many trainers to get to the leader, rinse and repeat. New players will need a real player to learn the ropes, as there's no learning curve here. The rental poke'mon for those who don't have a DS game to use are also very limited and basically impossible to get anything at all, as the way to get rentals is you'll need to return constantly to the 1st stadium to trade in your old poke'mon for your defeated opponent's poke'mon, which will usually be worse than your own. It'll really be bad if you find yourself playing after having beaten the game this way.
Final: only for the big time f
I have a DS, but let alone having a WORKING one, you have to buy another game, make progress on that, then transfer them so you can fight 3-D with no adventure to it. 3-D seems fun, but when you gett stuck with the presets, go find another 3-D pokemon game...
