Digimon Tamers: Brave Tamer

Digimon Tamers: Brave Tamer is the fourth and final game in the Digimon subseries for the Wonder Swan, and is consequently the one which concludes the story, ties together the Digimon Adventure and Digimon Tamers continuities, and finishes explaining who the hell that Ryo Akiyama guy is anyway.

After the end of the last game, Ryo is awakened by Monodramon, a small dragon Digimon, in a primitive jungle. Monodramon takes him to confer with ENIAC, the first electronic computer, the Digital World's first overseer, and the origin of the many different alternate Digital Worlds, able to access them in enclosed timeloops in order to prevent any changes to the timeline.

Meanwhile, Millenniumon has since been flung into the future and evolved into its final form, ZeedMillenniumon, and wielding the power to manipulate time and space, is now bent on conquering every timeline and dimension. Each of them resist his power however, so he begins to assemble an army. He notices the existence of ENIAC, and so sends a few mooks to test its defenses. In response to the impending attack, ENIAC assigns Monodramon as Ryo's partner to fend of the invaders, and that's when the fun begins...

The game plays similarly to the previous game, as a simplified Turn Based Strategy game. Each side can control at most three Digimon, and each turn Digimon can only make a single move. The novelty, like that of the concurrent anime, is the card system: cards containing the data of a Digimon's abilities can be bought or obtained from other Digimon, and can be used in battle to summon an attacker, heal, induce or remove status effects, and out of battle to upgrade a Digimon.

Tropes present in Digimon Tamers: Brave Tamer:

 * All There in the Manual: This is the fourth and final part of Ryo's unexported manual.
 * Big Bad: ZeedMillenniumon, again. Less expected is the revelation in this game, together with the previous ones, that Milleniumon is also
 * Canon Immigrant: This is the game that explains how Ryo is one to begin with.
 * Evil Counterpart: Inverted: Monodramon is the opposite of ZeedMilleniumon in almost every way.
 * Evil Knockoff: The Dark Tamers are this to Taichi, Daisuke and Takato, and their nine VR Digimon (VR-Apocaly, VR-Omega, VR-WarGrey, VR-Imperial, VR-Venom, VR-BlackWarGrey, VR-Duke, VR-SaintGargo, and VR-Sakuya) are this respectively to Apocalymon, Omegamon, WarGreymon, Imperialdramon, VenomVamdemon, BlackWarGreymon, Dukemon, SaintGalgomon and Sakuyamon.
 * Heroic Mime: Throughout the game Ryo is not particularly talkative, unlike in earlier games, and it is in fact ENIAC who recalls his past. Given the trauma of his experiences in the previous game, this may be justified.
 * Magnificent Bastard: ZeedMillenniummon, AND HOW. He earned the title when he managed to plan and execute undetected by an entity with access to all timelines, not to mention getting away with being responsible with nearly everything that went wrong in the Digimon Adventure continuity.
 * Multiverse: This game establishes and defines the Digimon franchise as one instead of a string of alternate continuities.
 * Multiversal Conqueror: ZeedMillenniummon, to an extent never seen before or again in the franchise.
 * My Own Grampa:
 * New Game Plus: When doing this, you get to keep all the cards gathered in the pervious game, and are given a new one with an... interesting effect:.
 * No Export for You
 * Shown Their Work: ENIAC really was the first proper electronic computer, and the Atanasoff-Berry computer [[http://en.wikipedia.org/wiki/Atanasoff
 * Trauma Induced Amnesia: Although it is not clear if it is simple amnesia or deliberate repression on Ryo's part.
