of course they should do a remake of the G/S series. except go based on the Crystal storyline. but, maybe they should do a remake on the Wii. with the Wii and Wii Remote's capabilites, Nintendo could:
*give you the ability to interact with your Pokémon inside and outside of battle; meaning that you can play with your Pokémon, like catch or what not. lol
*allow you to physically throw a Pokéball;
*allow you to battle Pokémon much like you fight monsters in FFXII; FFXII = Final Fantasy XII (12)
*allow you to physically pick berries off of trees;
*maybe have something to do with picking flowers to attract certain Pokémon;
*make Pokémon Contests and Pokémon Battles a lot more interactive;
*bring your Pokémon to life and give them a voice, much like the show.
those are some of the many ideas that i have that i think Nintendo should do with Pokémon (and what they should do with a G/S remake, especially if on the Wii).
