To fix Suikoden 1, just make graphics in Suikoden 1 better and characters that are killed in battles still alive after that.
Suikoden 2 need some changes as well. first make a better graphic. Then remove some unnecessary characters such as Mukumuku,Tuta,Gengen,Gabocha,Simone,Vincent because these characters sucks in battle and their appearance are hideous. They can be replaced by new characters that have better strength, some characters that can't be used for fighting such as Yam Koo and Tai Ho and change them as characters that can fight since they can fight in Suikoden 1 and better fighting strength while change some characters that can be used on fighting such as Hai Yo and change into characters that can't be used for fighting since not only his statistics sucks, his fighting style just seem stupid.
Grammatical error and spelling error need to be changed as well.
Rowd deserve to be punished as well. Rowd is a scum where he work together with Luca Blight for his own benefit and he show no mercy to Riou and Jowy. Rowd deserve to receive punishment such as being severly injured in battle in Riou's hand and being bring back as war prisoner, Riou told Rowd sister about her brother crime and Rowd receive punishment in death sentence.
Remove the bad ending. The bad ending where Riou ruinning away with Nanami really unnecessary as well as stupid. The only reason why Riou ruinning away from his fight is because of him listening to that useless characters called Nanami advice of giving up his fight. After leaving
Tinto,Riou and Nanami stay inside a house. When Shu and his parties come to that house, they founded Riou and Nanami to tell those two that Ridley was killed when he was looking for Riou and Riou was slaped by Shu because he want to abandoned his fight but actually is Nanami fault. When Nanami heard that Ridley was killed, she said stupid dialogues such as she has promised Genkaku to protect Riou, she doesn't want to see
Riou keep fighting with Jowy but she has caused more pain and sufferings to Riou and she keep saying sorry and Riou can decide what is best to him without considering her reaction but damaged has been done. This ending need to be removed.
Nanami deserve to be punished. Throught Suikoden 2, Nanami has shown that she is the most ugly,stupid,annoiying,useless character in Suikoden 2. Her dialogue are stupid, she tought herself is very charming whereas she is an attention seeker that will do what ever she can to gain attention, she is a control freak where when she saw Riou with other female characters, she will do what ever she can to stop Riou interact with those female characters.She is naive and stupid where she thinks that by persuading Riou to run away from his fight, he can avoid
fighting Jowy but she is just naive and stupid as her characteristics. Her dialogues are shoot, she keep saying those stupid dialogues throught Suikoden 2 and she will keep forcing herself into the party whereas players can choose better characters other than this stupid character
called Nanami. Change Nanami into character that are choosable and she does not forcing herself into the party anymore. Her fighting style in Suikoden 2 are silly also.
Not just only that, she is a pure coward when come to fighting. Remember when Dunan Liberation Army want to recruit a brilliant strategist and Apple recommended Shu? When they went to Radat, Shu throw a coin into Radat River and told Apple if they can found that coin, he will join them. When they are asking for person that in charge of that sluce gate to close that sluce gate for even one day only, stupid Nanami tell Apple to give up and When Riou and Apple are looking for that coin,Nanami keep saying that they won't found that coin but Riou and Apple does not give up on finding that coin. After Riou founded that coin, that shameless character called Nanami dare to celebrate Riou and Apple success. Shu is just testing Riou. If Riou followed advice of that stupid character called Nanami, Dunan Liberation Army won't recruit a brilliant strategist called Shu and peace will never arrived in Dunan.
Because of this stupid character called Nanami, Eillie doesn't have a chance to express her love to Riou. Eillie are way better than that stupid character called Nanami where she not just only love Riou but she also does not give up easily when facing obstacles. When Riou and Muse survivor reached North Window Castle, they are facing a lot of troubles yet Eillie tell them Riou does not give up and non of them should give up either. Based on this only, Eillie are way better than that stupid Nanami that only know to become attention seeker, saying stupid dialogues over and over again, a coward that only know to run when facing trouble. Riou should be having a relationship together with Eillie.
Everything about Nanami sucks, her hairstyle sucks, her face ugly, her dress style sucks, her fighting styles are hideous, her dialogue sucks hard, she is an useless coward.
Besides that, Pillika need to receive some changes as well. After she was shocked due to almost being killed by Luca Blight, compared to after she meet Jowy in Muse during Highland Occupation, Pillika should be able to speak after Muse was being captured by Highland due to Jowy's betrayal and Riou ask Pilika reason behind her unwilling to speak and Pilika will be punished if she refuse to speak for a long time and she manage to speak after she was being punished. Riou found Jillia and Pillika convoy and expose Jowy's crime. After Pillika found out that Uncle Jowy that she cared the most was actually working with her parents killer, Luca Blight, she become angry and condemn Jowy for his crime. After that, she apologize to Riou because she doesn't want to speak after Luca Blight almost killed her not just only she was shocked but also she want to receive more love from her beloved Uncle Jowy but she doesn't know that Riou and Nanami also cared about her, in her heart, she loved uncle Jowy behind of her parents and after she found out that her beloved Uncle Jowy actually working together with Luca Blight, her parents killer, she felt angry and condemn Jowy
Change the best ending of Suikoden 2 into ending like this: After defeating Jowy in Tenzan Pass, Riou take Jowy's Black Sword Rune and complete Rune of Begining, heal Jowy, take Jowy back to Dunan Castle and when Riou and Jowy found out that Nanami still alive, take her back to Dunan Castle as well. At Dunan Castle, Riou expose Jowy's crime and make Jowy realize his mistake by punish him on putting him into prison and expose Nanami action of keep telling him to give up on his fight, Nanami are being condemned for her action as well as receive punishment of be putting into prison for repeatly telling Riou to run away, Riou leading Dunan Republic to glory and Riou and Eillie become lover.
