A much more improved game after Pokemon Red/Blue/Yellow.
The graphics are much better then the first pokemon games. Still maybe a little dated to today's, but still were as decent as of today. And the pokemon looked like the pokemon in the art illustrations.
The gameplay was improved as well. You could battle certain trainers again if you have there phone numbers. The pokemon hold feature was introduced and open new possiblities. The game had two main quests, one in the new region and the other in the old region where the first pokemon games took place.
The sounds were better of course. Still dated to todays, but not bad at all.
The value... Like the first one we moved to today's pokemon games. But this game will not be forgotten as well by long devoted fans.
