The Kanto games are the best pok�mon games, Fire Red and Leaf Green are best. If Nintendo could do a remake of Gold and Silver then I would be delighted, since Johto games are next on the list. But a few things could be changed if you ask me:
Music: I don't really like a lot of the music in G/S. It could be changed a lot. Make it more like FR and LG but make it sound sharper.
Difficulty: we all know it, Pok�mon games are way too easy, I very rarely lose battles if ever in any of the games.
Chikorita: a pointless and crap starter. The only way this guy will actually be used is if people get all three. He might be good for Kanto but who the hell will be patient enough to get him that far? We should re-introduce Bulbasaur, he's a better Grass pok�mon at least. Or have Abra as a starter. That would be better.
Kanto: the Kanto section of the game felt dreadfully rushed to me. It should have been longer.
Trade: trading with FR and LG would be useful. Lets use the Wireless Adaptor for this. Link Cable is outdated.
Trade evolution: I hate trade evolution. It is the worst thing ever created in pok�mon games. Nintendo and GameFreak screwed up there. If they have to make trade evolution why can't it be something crap like Ratata or Weedle or Caterpie instead of Kadabra, Machoke and Haunter?
Pok�mon: they'd better not include Hoenn pok�mon. FR and LG included Johto pok�mon which was a bad idea even though Johto pok�mon are cool. The hoenn pok�mon look like Nintendo picked a few random creatures out of the animal kingdom and jammed them together to make a pok�mon.
Phone: unless you could have unlimited numbers stored on your phone and make it so every time someone calls you they want a battle they should get rid of the phone and introduce the VS Seeker to Johto.
And good news, apparently Nintendo plan to make a re-make of all pok�mon games they haven't re-made yet. So good news to you all, it's probably going to happen. AND THEY BETTER INCLUDE MY CHANGE IDEAS BECAUSE MY IDEAS ARE BEST!
I'm finished here...
