When it comes time for a character to bow out, it's important to capitalise on the unique relationship only gamers can have with their characters. We've most likely grown to love certain people over the course of a game's runtime - sometimes close to hundreds of hours. Death in these sorts of narratives is when gaming borrows the most heavily from film, with the vast majority happening in cut-scene rather than gameplay. Many will remember that scene from Final Fantasy VII where a downright loveable teammate we'd started to genuinely care about was taken away, simultaneously establishing one of the greatest villains in gaming history because of it. It all worked so well we because of the time spent with that particular character beforehand, and as becomes evident with some games - it's a mix of gameplay and cutscene that packs the biggest punch. Another factor when creating someone we're going to love to hate - or a hero we going to love to embody - is that gaming as a medium is far more susceptible to sequels and reboots, meaning it makes far more sense to keep a character alive. Sure, Hollywood is no stranger to letting only a few years pass before forcibly Frankenstein'ing together another incarnation of a popular series (Spider-Man, anyone?) but still, gaming's library is comprised of a whopping 70% of sequels overall. It's a pretty staggering statistic, and therefore if creators are actually going to kill someone off for good, it has to be worth it, and in a way that does the character the utmost justice in retrospect.
