It also contains Canas, who joins the party happily married in Fire Emblem: Blazing Blade, although his wife does not appear. In Fire Emblem: Binding Blade (which is a chronological sequel to Blazing Blade) it was established that Canas's son Hugh was raised by Canas's mother Niime, resulting in Canas's death being written into the ending of Blazing Blade. This resulted in the fan meme that Canas was "killed by continuity errors".
More tragic example from Sacred StonesSir Orson and Monica were Happily Married... But as she was an Ill Girl, she perished at some point before the story, and Orson was driven mad and evil due to this. Lampshaded by Seth before the fight with Orson, who mentions that their happy marriage was famous among the Renais knights.
In the Path of Radiance/Radiant Dawn continuity, there are Calil and Largo. Geoffrey and Elincia can be this if they get an A support, and the same goes to Micaiah and Sothe if their own A support stays.
Awakening, Fates and Three Houses has the players pick-and-choose whether their charas marry or not. Those who do get married tend to fit in here near all the time, however.
Kingdom Hearts has (in theory at least) Mickey and Minnie Mouse. Since they rule together as King and Queen, it's not unreasonable to presume they're married, although it's never explicitly stated that they are.
Prior to this they were married with children in Mickey's Christmas Carol, where they played the Cratchits; they also appeared to be married in a dream sequence in Mickey's Nightmare. A particular quote of Walt Disney's from 1933 tends to float around, stating that "In private life Mickey is married to Minnie..." Fans tend to either shrug this off or take it as canon; either way, the main consensus seems to be to keep them eternally courting as to not "spoil the illusion of youth."
However, Mickey and Minnie's voice actors, Wayne Allwine and Russi Taylor, were, in fact, married; Allwine has since passed away.
Aribeth and Fenthick were on their way there before Fenthick's trusting nature got him executed at the end of the first chapter of the first campaign. He only existed to give Aribeth a reason to turn to the dark side, anyway.
Two of your units, Karl and Lynn, in Valkyria Chronicles are Happily Married and a full-blown Battle Couple to boot. At the end of the game, after the war, Largo and Cpt. Varrot and Welkin and Alicia also marry.
Atrus and Katran of Myst, in contrast with their epically screwed up family in general. And if those two had paid more attention to what their kids got up to, the Stranger could have avoided twenty years of troubleshooting.
Saavedro and Tamra count as well (that is, before Sirrus and Achenar arrive on Narayan...) Sadly, it's never clarified if she survived/stayed single in those twenty years when Saavedro was trapped.
Maxim and Selan embody this in Lufia II: Rise of the Sinistrals, doubling as a Battle Couple, even up to the point where Maxim dies nearly right after Selan, and only after making sure that Doom Island misses destroying thousands of people, including their son.
Sue's parents in Mitsumete Knight. Influenced by this, she seeks her ideal husband and wishes for this kind of relationship with him.
Cecil and Rosa of Final Fantasy IV, at least after the credits and in the sequel. The only primary couple in the main Final Fantasy series to date that has managed this, astonishingly. While some other pairs are implied to become this later, Zidane and Garnet of Final Fantasy IX most prominently, only Cecil and Rosa have officially tied the knot, which is what this trope is about. Yang and his wife also qualify.
Final Fantasy VI has a tragic example. Cyan and his wife Elaine were appearently this. Before her death.
Final Fantasy VIII has two examples, Cid and Edea and Laguna and Raine. Prior to her death as well.
John and Abigail Marston of Red Dead Redemption. Even though Abigail is held hostage for most of the game, John turns down the advances of many women, and does everything within his power to get his family back. And eventually he does.
Part of the Harvest Moon experience is the player character becoming Happily Married to the bachelor/ette of their choice. Supposed to be a small part of the game, but Popularity Power means that it's grown in importance as the series continues. That aside, within the games themselves are several (dozen) NPC couples, the majority if not the entirety being Happily Married.
Subverted in Harvest Moon DS (Cute) where, when you talk to the rival couples after marriage, all but one couple seem to voice doubts about the marriage to the player.
Umineko is impressive by managing to have two very unexpected Happily Married couples; Eva and Hideyoshi, in a family full of internal squabbling and backbiting, manage to be good, loving spouses. She snaps as soon as he dies, showing that the marriage is really Eva's rock concerning her sanity. And secondly, and doubly impressive is Battler/Beato, counting as a bizarre combination of Happily Married and Unholy Matrimony; Battler is The Hero, and Beatrice is The Chessmaster. Everything suggests that they honestly enjoy challenging each other, though, and it might just be a pillar of their happy marriage.
King's Quest: Graham and Valanice seem to be doing pretty well for themselves, Alexander and Cassima also seem to be doing okay, Cassima's parents seem happy, and it's pretty much assumed that Edgar and Rosella will go here...eventually. In the Fan Remake of King's Quest IICaldaur and Lavidia, Count and Countess of Kolyma also are still quite in love.
Let's not forget Citan and Yui of Xenogears, who were a Battle Couple in their younger years.
Guilty Party has Butch and Charlotte. They may differ in age,height, and even ethnicity, but they're a Battle Couple and Butch is a hopeless romantic anyway. Interestingly, the game's other couple, Dorian and Olivia, is a toss-up between this and No Accounting for Taste--they clearly love each other despite the fact that they argue all the time, but, well, they're also one another's arch-nemeses. Dorian knew this, and still somehow doesn't care.
Khalid and Jaheira of Baldur's Gate. Sure, Jaheira is bossy around him but their marriage is a happy one. She also cries when Khalid dies. The player character can also be married with either Jaheira, Aerie and Anomen.
The world of Dragon Age seems significantly more accepting of extramarital affairs than a normal medieval setting, so the only romantic pairing in either game in which the player ends up getting married is with a female Human Noble Warden and Alistair in the first game. Aveline and Donnick end up Happily Married in Dragon Age 2 if Hawke helps out.
Other examples include Bryce and Eleanor Cousland, who stay together in their last moments, Fergus and Oriana Cousland until she and their son Orin are killed, Delilah Howe and her husband Albert, as revealed during Nathaniel's personal quest, Danyla and Athras but only continue to be so if you take one of the few scenarios where she doesn't die, Cyrion and Adaia Tabris, Aveline and Wesley Vallen until he dies from the taint, and Leandra and Malcolm Hawke.
Golden Sun is pretty good at stable families, even when wrecked by disasters. However, the grand prize of this trope goes to Briggs and Chaucha in The Lost Age, whose subplot pretty much consists of each one digging themself a deeper hole and getting bailed out by the other, with help from baby and grandma. The Badass Family that delves into crime together...
Even Briggs's death in Golden Sun Dark Dawn can't ruin this trope-- as he's dying, Briggs worries about Chaucha's well-being.
Catherine: In the game's "True Lovers" ending (one of several true endings), Vincent and Katherine get married. Orlando and his ex-wife even decide to give it another chance as well. Happy endings for everyone!
The King and Queen of All Cosmos from Katamari, as shown in We Love Katamari and Katamari Forever.
Kenny and Katjaa in The Walking Dead: Season One, who have a son, Kenny Jr., nicknamed "Duck". This is tested after episode 1, but even after everything they go through, Katjaa tells him that she loves him very much before heading off to put Duck down. Family means the world to Kenny, proven by his depressed state after he loses his family, as well as his role in season 2.
