Do a lot more stuff you can't do in the originals...
Graphics: 9/10 (sublime)
The Pokemon actually have color rather than just red, the Third-person veiws were a nice touch, and the places you go are more detailed. Also, the pokedex with the enviroments, they look awesome! Also, the Pokemon attacks are way better!
Sound: 8.9/10 (magnificent)
The music is a little different, but a little better, Pokemon cries are the same thing as before, and the sounds are not too different. The sound is good.
Gameplay: 9.1/10 (sublime)
It's the same thing, only you get to do a crapload more stuff, like I said before.
Camera: 10/10 (flawless)
The camera is perfectly centered on the trainer, who is in the middle of the screen, no flaws here...
Difficulty: 6/10 (average)
This doesn't count against the score, but it's about right for anyone.
Humor: N/A/10
This doesn't count against the score either, it's just not made for this.
Controls: 9.4/10 (sublime)
Same old controls...
Plot: 9.2/10 (sublime)
Become a Pokemon trainer, fill the Pokedex, thwart Team Rocket, beat the Elite Four, explore the Sevii Islands, catch pokemon, get the Ruby and Shappire for you to trade, trade with Ruby, Shappire, and Emerald, there's a crapload of stuff to do.
Overall: 9.5/10 (sublime)
Ok, that's it, get out of here, or I'll fire mah lazer! Bwwahhhh!
