Pokémon X and Y

The first main-series Pokémon games in full 3D, Pokémon X and Y are set in the faraway region of Kalos and feature 69 72 new Pokémon, a huge regional Pokédex separated into three sections, and brand new features such as Mega Evolution, giving Pokémon from previous games a new look, stat boosts, and the occasional type/Ability change for the duration of a battle.

Also, fashion and cafés. It is the equivalent of France, after all.

Version 1.1
On October 25, 2013, a patch was released on the Nintendo eShop for both games. The patch contained update data for the games, updating the game to Version 1.1.

Besides "Ver. 1.1" being added to the bottom screen of the main menu, the patch fixed two problems:
 * In the original version of the game, a nasty bug occurred when saving on the Northern and Southern Boulevards of Lumiose City. When the player saves the game, the game may freeze, forcing the player to reset the Nintendo 3DS system. However, when the game is reloaded, the save data cannot be loaded. Along with fixing the glitch, the update supposedly repaired the corrupted save data for anyone who was already affected by this glitch.
 * In the original release, the filtering system of the GTS was bugged, and using certain filters would crash the game when confirming a trade.

Version 1.2
Another patch update was released on December 12, 2013, containing an update to Version 1.2. The patch also contained the v1.1 patch for those who had not yet downloaded it. The "Ver. 1.1" text on the main menu was changed to "Ver. 1.2".

Version 1.2 fixed the following problems:
 * Pokémon that evolve by trade not learning new moves after evolving if received through Wonder Trade.
 * Various PR Studio captions not being unlocked even after fulfilling the requirements.
 * The final fix was branded as "updating an Internet communication issue". This fix was actually a patch to the online battle and trade to fix the following oversights:
 * In online battles, the data from the player (i.e. a move that was chosen, a Pokémon to be switched out, etc.) was immediately sent to the server as soon as it was ready, unlike previous games, in which the data would be sent after both players had finished selecting their next move. This spurred devious hackers to create a program called the "Battle Analyzer" that would read the data that was sent from the opposing player, allowing them to unfairly predict and counter their enemies' strategies.
 * Within the game, the player had a select "Shiny Value" (SV) that would determine the probability of an egg hatching into a shiny Pokémon. A program called "Instacheck" was created to help determine this value and match it with other players, allowing them to receive eggs through online trade that were guaranteed to hatch into shiny Pokémon.

The v1.2 patch is now required in order to connect to the Internet and use online features. Once the patch is downloaded, players will be able to participate in Rating Battles, which were disabled for several weeks following the release of the Battle Analyzer exploit.
