I have fully completed every RPG I ever played, even the horrible ones that you don't honestly want to play anymore but for the sake of getting it over with you do. I cannot honestly say why I do it; I suppose it is just because I hate losing. For me, missing out on something in a game is losing an experience that I could have had. Of course, if I never knew about the existence of the event then it would not grind my gears so to speak. Somehow they have a way of coming to my attention though.
The Tynar Rouge on Agrias' birthday (
Final Fantasy Tactics: The War of the Lions) was an experience that was worth throwing away 70 hours of work and restarting the whole game for. It doesn't hurt that it is arguably one of the most broken Female Only accessories in the game.
Lipstick, not just for looking good anymore.
Jam it back in, in the dark.
