Yes, the main difference is that in ruby, you can only catch groudon and maybe rayquaza (not sure). In emerald, you can catch rayquaza, kyogre, and groudon. All of the games are great though and there may be a few other minor differences, like which pokemon appear on a certain route. I know that in the town with Brawly as the gym leader (fighting) in th cave there are sableye in ruby, but not in salphire. Personal preferance is emerald because it is a mixture of ruby and saphire. Have fun!
they are 2 different games.
No, you have to migrate it from Pokemon Emerald, Ruby or Sapphire. No, you have to migrate it from Pokemon Emerald, Ruby or Sapphire.
you cant but you can trade it from ruby, sapphire, and emerald or use the action replay.
Kyogre Is Not Avalible In Pokemon Ruby. Just In Pokemon Sapphire/Emerald
you really should get emerald cause Pokemon ruby and Sapphire are separate and emerald is those 2 put together so instead of getting ruby and getting groudon just get emerald and you can get groudon and kyroge and newer Pokemon
in my opinion emerald is way better than ruby. that is because there is battle frontier in emerald and in emerald we get a jotho starter pokemon from prof. birch after beating hoen dex!
you cant its a Pokemon from emerald
Emerald by far
you can't Pokemon from diamond and pearl cannot be trade with Pokemon from ruby, sapphire, or emerald. the only ones that are different regions are fire red and leaf green can trade with ruby, sapphire, and emerald. or you migrate to diamond and pearl from fire red, leaf green, ruby, sapphire, or emerald. hope this helpd.
no its in ruby,saphire and emrald.
Sapphire and Ruby were released at the same time, then Emerald was released later.
You can't get Kyogre in Pokemon Ruby but you can get Kyogre in Pokemon emerald and sapphire and in ruby you only get groudon and rayquaza. In sapphire you get Kyogre and rayquaza and in emerald you can get groudon, Kyogre, and Rayquaza.
