Fire Emblem as a WHOLE has this in spades. Thanks to the support system, which gives characters both nifty Character Development and stat bonuses, Fire Emblem tends to be a breeding ground for Ship-to-Ship Combat with the unique difference that Shipping in Fire Emblem - and thus arguments thereof - is often concerned with gameplay viability as much as it is with the romantic dynamic between the characters. It doesn't help that several fans view certain ships as a better couple. The gameplay for the series actually allows the player to do this in game - with Perma Death in near-full effect across the games, if you don't like a character, you can intentionally use a Uriah Gambit to get the character out of the way.
