1) Some nice Gym Battles 2) A very wet map. 3) A really annoying bike system.
A few of my favourite Pokemon come from Gen III, so I won't rag on the designs too much. But I'm right there with you on how dumb the starters look. --- "We have no loofas in the Palace of Wisdom" - John Morrison
Or, at the very very least, play XD: Gale of Darkness.
Yes, these were wicked.
I'd say if you're a Pokemon fan, you'd probably enjoy the experience. If you liked Gen IV, there's no reason you shouldn't like Gen III for the basis that it wasn't Kanto/Johto. It was revolutionary in its graphical overhaul, and I think it was pretty great. As said before, I'd get Emerald instead of R/S, because Battle Frontier was amazing. The Battle Frontier was worth it just for the challenge- I still play Emerald just for it.
If you loved Gens I and II, then you'd probably like Leaf Green and Fire Red. It's a good compromise with your favorite old Pokemon. --- Official Bulbasaur of the Pokemon X boards.
