1. Whats so special about this game is that you can fight anyone online in full 3-D and you can customise your character however you want including the phrases they use. This game gives you a chance to test how strong your team is both online and offline as the computer team setups can get extreamly difficult to beat.
2. It does not have an adventure mode like either one of the games. You are restricted to battles only.
3. No mini-games and you cant trade PKMN back to D/P as it sends a copy of everything on your game. No more catching. The only trading you get to do is if you use the premade passes that have weak pokemon. Eventually you get to trade those with other people you fight.
4. I bought it because I like to battle other people online and test my teams. The custom character was cool too. Also it kept me active on my
DS game as I kept making stronger teams so I could beat those though comp teams and show off my team online. I also liked it cause unlike
DS you dont need
FC's and that it was in 3-D which makes the battles way cooler.
5. I rather enjoyed this game it just depends on how much you play Pokemon and whether you have wi-fi or not.
I hope that satisfies your needs. Good day to you too! :D
