Yu - Gi - Oh ! The Duelists of the Roses Yu - Gi - Oh ! The Duelist of the Roses is a video game for PlayStation 2 in the " Yu - Gi - Oh ! " series , is loosely based on the real - world English Wars of the Roses . This game ' s characters , as well as the Japanese name of this game , suggests that this game is a continuation of the Yu - Gi - Oh ! Forbidden Memories game . As such , it is widely regarded as its spiritual successor . In mid 2006 , Duelists of the Roses was named a PlayStation 2 Greatest Hits title . Characters . Most of the characters are based on characters from the Yu - Gi - Oh ! anime and manga , but given names and / or roles to portray a historical figure . Some characters simply have the same or similar names as their anime / manga counterparts and aren ' t based on historical figures . For example , the character Bakura isn ' t based on a historical figure named Bakura . Story . Yami Yugi assumes the identity of the head of the Tudor dynasty , Henry Tudor , while Seto Kaiba represents the head of the Yorkist forces as Christian Rosenkreuz . The player assumes the role of the Rose duelist , who has been summoned to aid the Lancastrians by Simon McMooran , a Scottish Druid at . However , Christian Rosenkreuz shows up and then the player decides which side he or she is going to be a part of . In order to get back home the player needs all 16 of the " Rose cards . " 8 Red Rose cards are held by the Lancastrians and the 8 White Rose cards by the Yorkists . The White Rose cards have created a barrier that keeps Yugi ' s forces out of Britain , effectively keeping the Yorkists in control . The player can choose the Red Rose for the Lancastrians , or the White Rose for the Yorkists . Each side has different opponents and different endings , but there is an option to restart the game after completion to travel the path you did not choose the first time around . If you choose the path of hero , Seto respects your choice and lets you leave in peace . After meeting Yugi and learning more about the situation , you are returned to Britain , where you fight Seto ' s minions , the Rose Crusaders - Rex Raptor , Weevil Underwood , Labyrinth Ruler , Keith , Ishtar , Necromancer , Darkness Ruler and Pegasus Crawford . All but Pegasus will give a card as he does not have one ; Seto keeps it on him at all times . After defeating the Yorkist King in a duel to pass time , Yugi ' s forces will kill him and his forces in battle , leaving you to head to Stonehenge and retrieve the last White Rose Card from Seto . However , he reveals the duel to have been part of ritual , summoning Manawyddan fab Llyr to enact a pact to ensure his family has power . However , the player defeats the guardian , sending him back into nothingness , defeating Seto and being sent back home to the future , leaving the Rose Cards behind . If you choose the path of selfishness in wanting to go home , you will face Yugi ' s friends and allies . However , unlike in the first scenario , it ' s basically a gauntlet - one duelist after another , no choice in who to fight . To get all the Red Rose Cards , you face Tea , Tristan , Mai , Mako , Joey , Shadi , Grandpa , Bakura , and Yugi . Upon winning the needed cards to get home , Seto is quite grateful to you and summons Manawyddan fab Llyr to enact a pact to ensure his family has status and wealth through the ages , and yours as well . However , it turns out to be the wrong guardian , who is extremely angry that he has been summoned after his brother was summoned and sealed away in Egypt . Defeating him to save the world , the player is thanked by Seto for helping in his selfish plans , apologizing for the trouble . He gives the player a White Rose Pendant , vowing that if it ' s shown to his decendants , they will do whatever they can to help , making the " Pact of the Rose " . Seto sends the player back home and disbands the Rose Crusaders , allowing Yugi to get past the barrier keeping him out and win his throne back . Gameplay . The dueling rules differ from the ones that are in the present time in that they are under the " Perfect Rule . " In this way there is a crude form of movement and a Deck Leader . Deck Leaders are monster cards that are needed to play cards from the hand ; they represent your Life Points ( LP ) . Any attack to your Deck Leader is considered to be a Direct Attack to your LP . Card movement is a simple card moving rule where you can only move the cards left , right , forwards , or backwards on the field . This movement capability is multiplied when there is a terrain movement bonus . On a " Favorited " terrain ( depending on type ) , monsters get 500 ATK and DEF boost , similar to the fields in Duelist Kingdom . Only 1 card may be summoned per turn , and Summoning Points equal to the level of the monster are required to summon monsters . 3 Summoning Points are gained each turn . Each card has a Deck Cost which can be used to determine the overall power of the card . Each card that is added to the deck increases the Deck Cost by the card ' s cost ( e . g . a card with a cost of 24 will increase the deck ' s cost by 24 ) . During the Campaign Mode , you cannot duel someone if you have a higher total Deck Cost than your opponent . This helps to keep players from completely dominating their opponent . The Duelists of the Roses shows the monster itself hovering above the card when it is face up on the field . When monster battles are set to " Display " in the options menu ( which you can bring up at any time during a Duel ) when two monsters come into contact the screen switches to a detailed arena representing the current field terrain with the two monsters on either side of the arena . After a few moments the two monsters battle and the winner then roars or dances its approval over the victory of the battle if it was the one who attacked .
