I'm positive that there is not a single Electric/Rock Pokémon in the game.
Anyhow. I've wondered for quite a while now why people disliked 4th gen so much but liked 5th gen. I mean, 4th gen had nice Pokémon in it, and the story wasn't that bad at all. It felt like a sequel to 3rd gen (Hoenn<3) somehow.
5th gen's biggest turn-off for me was the graphics... Sure, overall it looked better than all the previous games combined, but the sprites of your Pokémon in battle were the worst since 1st gen. Big deal that they moved in battle when every image of your Pokémon in battle was not very sharp. Anyone else with me here?
