It's favorite and in your previous topic it's Lugia.
Onto the topic, 3rd Gen for me :)
actually, Favorite is the way you americans (or whomever you may be) spell it. i cant say for the TC but I'm australian and here we spell it favourite. so the TC may have it correct. and on to the topic. My favourite gen is Gen III, absolutely loved Hoenn, still do. Do i think VI will take thee top spot? it may, but i doubt it.
We must stand as a bulwark against the selfish, the souless and the mad. But above all, For The Greater Good!
Gen II is definitely my favorite. Not just because I grew up with it, but because I loved all of the new features like Dark and Steel type, held items, and night and day, being able to go to both Johto and a reimagined Kanto, and to me it had both the best Pokemon designs, and the best NPCs.
