Sure. The main character of Lost Odyssey is immortal and has lived for around a thousand years. He inhabits the typical role of the quiet, stoic, non-talkative protagonist, which initially turned me off, but as you play, various vital memories are triggered in his mind. They don't relate to the central story, and they're presented as text on a painted background, with no visuals, no voice acting, and only the slightest hint of a score. I really can't do justice to how beautifully these scenes are executed or how well they're written, but they're touching, surprising and often devastating. It's the calming, almost sobering plainness of their presentation that makes them work so well.
Kaim (as he's called) isn't really bitter, angsty or antisocial; he's just a man who's lived a thousand years and has endured far too much for anything to greatly affect or move him anymore, which isn't to say he's an emotionless brick, but that he's already carrying quite a lot of weight. I've seen plenty of JRPGs use this archetype, but few, if any, that really explore that mindset. It usually seems like a lazy shortcut, i.e. using a stock character and then throwing in some contrived explanation for it late in the game. Kaim, on the other hand, is perfectly characterized. I sympathized with him more than I have for 99% of the RPG characters I've seen.
You exist because we allow it. And you will end because we demand it.
