This game is great. Most fun I've had in pokemon since Gold/Silver. I just got the third badge and have put in like 30 hours already. My current team:
Gardevoir
Charizard
Greninja
Doublade
Tyrunt
Pikachu - should evolve him to Raichu but he's so damn cute.
I also have that panda bear fighting/dark one for when I need a fighting pokemon.
I agree that the game has been pretty easy so far. With the changes to make exp much easier to come by (Exp Share as a key item, not reducing exp for swapping out pokemon, getting exp from captured pokemon) they should have ramped up the difficulty of the gym leaders and Elite Four. I haven't gotten to the Four yet but I expect them to be pushovers due to me currently being about 10 levels higher than any trainer's pokemon (and I haven't really grinded at all).
