The original Devil Survivor was my first Shin Megami Tensei title and one of the first SRPGs I played. Not only was its gameplay incredibly memorable, its narrative scarred me for life when a careless decision on my first playthrough got one of my favourite characters killed. I remember it being quite difficult and requiring a lot of grinding, but the story was good enough that I did the grinding without too much complaint. And the cast still features some of the better character writing in the entire MegaTen franchise. Poor Yuzu sure did get shafted, though.
