Emerald:
You can get Kyogre&Groudon;
You get Rayquaza... Before the league.
You can get one of the three second gen. Starters.
You can get all the Johto Pokémon that weren't in Fire-Red/Leaf-Green.
You can catch... Mew! As well as Ho-oh, Lugia and Deoxys, but you need either Action replay warp code (my case) or Nintendo events.
You access the Battle frontier, where you can get decorations for your secret base, ones that you couldn't get in R/S!
And the best of all... There is no Berry Glitch! ("The internal battery has run dry, The game can be played. However, time-based events will no longer occur.")
