The gameplay is mostly unchanged from the previous games; the player controls the main character from an overhead perspective, and the controls are largely the same as those of previous games. As with previous games, the main objectives are to catch all of the Pokémon in the games and defeat the Elite Four (a group of Pokémon trainers); also like their predecessors, the games' main subplot involves the main character defeating a criminal organization that attempts to take over the region. New features, such as double battles and Pokémon abilities, have been added. As the Game Boy Advance is more powerful than its predecessors, four players may be connected at a time instead of the previous limit of two. Additionally, the games can be connected to an E-Reader or other advanced generation Pokémon games.

Pokémon Ruby's updated graphics with weather effects, amazing sound, more than 200 Pokémon with over 100 new species--as well as its faithful adherence to the existing series of Pokémon games--makes for a welcome evolution in the series.

First, the game has a lot in common with Pokémon games Silver, Gold, and Crystal. For example, players can choose to be a boy or a girl trainer, an internal clock sets events at certain times, and you're the game's handy-dandy Pokédex helps players keep track of the many stats. You're main goal is still to beat all the Gym Trainers and become the Pokémon Master. If you've played the old games, you will be right at home. But not all is the same.

The most obvious change is in the battles themselves. Now that two Pokémon can fight on your side at the same time, you can tag-team them against an enemy by taking advantage of the strengths of your Pokémons while covering their weaknesses. For example, you can now have a water Pokémon watch your fire Pokémon's back. You can also attack more than one Pokémon at a time.

A whole new element to the game focuses on how berries are used in battle. And if you collect enough berries, you can take them to a Berry Blender and make a PokéBlock, which is a little super-charged candy that raises your Pokémon's "Condition" attributes. You can then groom your Pokémon for regional contests and compete for ribbons like "Best of Show," which will unlock additional contests. There's even strategy in how to best use your berries: pick too many and the berry tree will disappear; plant berries, though, and a tree will grow. You can also build a Secret Base in special areas of the game, which you can decorate just like you can your room.

And let us not forget that Pokémon Ruby has a kickin' multiplayer system, too. You can trade Pokémon, and link up to four players for incredible battles. The only downside is that you can't link up with the old Game Boy Color games.
