The first thing that most gamers notice when they begin playing Emerald is that it seems to be a lot like Ruby and Sapphire -- well of course it is!  Emerald is what they call the Bridging Game for those two.  In the Pokemon Game World the games are released as complimentary color-based pairs, with each having a slightly different set of Pokemon in it, and a different legendary.  The Bridging Game is basically most of the contents of both games joined into one. Now if that was all that there was to it, a lot of gamers would skip the main games and just wait for the Bridging Game to come out, but that is not actually all that there is to it, mates.  The blokes at Game Freak use the Bridging versions to add in additional content and story to the games, so while they are similar to the first pair they are also uniquely different.  There are also a handful of Pokemon in each bridging game that have to be obtained from the two color-matched games that cam before it.  The general trend is for gamers to buy one of the first pair, battle and trade with a mate who has the opposite game, and then get the bridging version to play as their base game in preparation for the release of the next generation.
